About this property

Key Colony Beach oceanview condo, beach + heated pool

  • Welcome to The Little Mangrove, your pristine oceanview home base at Sea Isle Condominiums in Key Colony Beach. Start mornings on the balcony with wide blue-water views, spend the day on Sea Isle’s sandy beach or by the heated pool, then head out for boating, snorkeling, and the best Middle Keys dining in nearby Marathon.

    This is the kind of place guests return to for the calm, walkable neighborhood feel, easy beach access, and a comfortable, well-equipped condo that’s perfect for two couples or a small family.

    Why guests love it:
    • Pristinely clean well kept condo
    • Oceanfront balcony with beautiful water views
    • Sea Isle private sandy beach + heated pool
    • Tiki hut + grills and shuffleboard
    • 2 bedrooms, 2 full baths (ideal for two couples)
    • Fast Wi-Fi for remote work and streaming
    • Dedicated parking space #21
    • On-site coin-operated laundry
    • Well equipped kitchen for easy meals at home
    • Walkable Key Colony Beach (don’t miss Sunset Park for sunsets)
    • Fishing and Lobster gear avaiable for use in guest bedroom closet (2x poles with small tackle boxes, two lobstering sets)
    • Beach and lawn chairs in 2nd bedroom closet for use

    The space:
    • Sleeps 4 max (including infants)
    • Primary bedroom: King bed + ensuite bath
    • Guest bedroom: Two full beds
    • 2 full bathrooms
    • Open living/dining area, well equipped kitchen, and oceanfront balcony

    Location: Key Colony Beach is one of the most laid-back, guest-friendly spots in the Keys. You’re close to local restaurants, bike paths, and parks, with quick access to Marathon, the Seven Mile Bridge, fishing charters, snorkeling, and diving.

    Good to know before you book:
    • Third-floor walk-up (stairs only, no elevator). The views are worth it, but it’s not a fit for guests who need step-free access.
    • Check-in: 3:00 PM
    • Check-out: 9:00 AM (cleaners arrive right at/after 9)
    • No pets (Sea Isle is pet-free)
    • Quiet hours: 10:00 PM to 8:00 AM
    • No smoking/vaping inside the unit
    • Sea Isle common-area amenities are subject to posted community rules/hours.

    Note: Key Colony Beach requires a 7-night minimum (City ordinance Sec. 9-24). Longer stays are welcome. Saturday-to-Saturday is our usual pattern, not a requirement. Any-day check-in is fine if the stay is 7 nights or more.

Great location and beautiful property. The condo had everything we needed including great views. Sunset park was a short walk and a great little spot to enjoy the sunset. There are a couple restaurants within walking distance and lots of amenities within a short drive. Highly recommend!

We had a wonderful time in Key Colony. The Sea Isle Condo was great and met our needs. The beach and lounging lawn were comfortable and had great views. We woke up to watch the sunrise each morning with a short walk to the beach.

We enjoyed our stay at this property. Michael, the host, was very accommodating. He truly made us feel welcomed and was attentive to every need. The condo unit was clean and well appointed. I enjoyed sitting out on the balcony in the mornings looking out over the private beach and pool. I would highly recommend this property for anyone visiting the Keys.

Great Week

The property was great for our week long stay. We enjoyed the walks on the beach and the hours by the pool. The neighbors were friendly and welcoming and shared places to eat and things to do. The condo was just the right size for 4 adults and was quiet. Michael was great to work with and available for any questions or problems. The only issue would be if you have a problem with stairs.

Key Colony Beach was everything we’d hoped for a winter getaway

We loved everything about our stay at Key Colony Beach! The apt was spotless and spacious, kitchen had everything we needed and the breezes off the ocean were so relaxing. Water aerobics an option, pool was sparking clean and sunny and everyone was so welcoming. And of the course the ocean was fabulous. We had a gourmet dinner every night. Finally,’our host, Michael, was terrific - immediately responsive and helpful (we were inquiring about EV charging). Great vacation! We’re definitely going back. .

Home away from home

This property has all the amenities of home with an amazing view, private beach and beautiful pool. The full size kitchen that was stocked with all the pots and pans was perfect for making meals for my family. The bedrooms and bathrooms were clean and spacious; plenty of towels and great water pressure. The sandy beach was beautiful and we found many sea creatures to entertain us. Property owner, Michael, was fantastic and informed us of all things "Keys" to do with the kids. Steps from the condo was Sunset Park, where the whole neighborhood gathers to watch the sunset together... singing the Marathon Song aloud! 🎶 We loved it and will definitely return!

Great place to stay in the Keys

This was our first visit to the Keys but I hope it won't be the last! We had a great vacation. We have in many vacation rentals and surely this one ranks at the top of the list. First, Michael is a wonderful host who makes vacation planning easy. Next, the condo itself is great. The beds are comfy, kitchen is well stocked, the place is clean and seems to have everything you could need or want. The beach is amazing, we often had it and the pool all to ourselves. The Key Colony neighborhood is safe and quiet. Sunsets are amazing. We snorkled at Looe Key from Bahaia Honda State Park, visited the turtle hospital and Dolphin Research Center, spent a day in Key West, kayaked at Curry Hammock and enjoyed the beach and pool. You cant go wrong with this condo! Thank you, Michael!

Great location, wonderful family friendly stay!

We lived everything about our stay! Prior to arrival communication with the owner was wonderful. We received an email with information about the area/restaurants/activities that was very helpful and the restaurant suggestions were all amazing! Check in was very easy. The condo was clean and well stocked, exactly as pictured. The pool area was perfect. It wasn’t very crowded, but there were plenty of lounge chairs and shaded table seating. The beach area was beautiful as well. The kitchen was well stocked with everything we needed for cooking. Paper towel, toilet paper, laundry soap, dish soap were all provided. Beach towels were provided, but if you have little ones that need a dry towel multiple times a day you may want to bring extra or quarters for the dryer (2.00 for washer/2 for dryer). The neighborhood was great for morning walks and Sunset Beach is just down the road for beautiful evening views! We loved our time here and would absolutely stay with these owners again!

Paradise found

We stayed at this condo for one week to celebrate our 30 year wedding anniversary. The condo was perfect for our needs. I enjoyed the private beach and sunsets at sunset park beach. There is so much to do and Michael was great at giving recommendations for all the activities. We rented kayaks and went to Curry Hammock state park. We went snorkeling at Key West with Fury. Loved it! We went reef fishing on the marathon lady party boat and caught a bunch of grunt fish which we ate for dinner. We visited Crane Point also and it was worth the $15 entry fee I think. The beaches nearby are just gorgeous; Bahai Honda state park beach is stunning and a sunset at Sombrero a must. We ended our stay with a fantastic meal at Butterfly cafe. Exceptional service and food. Thank you Michael for sharing this lovely place!

Fantastic stay!

We absolutely loved this condo!! Everything about this property was perfect- the location, the gorgeous beach (a rare commodity in The Keys), the beautiful grounds, and the awesome pool. The central location was perfect for exploring the Keys in both directions. Michael was a phenomenal host. He called before we left for vacation with check-in instructions and many suggestions for a perfect stay. The condo itself was beautiful and extremely well-stocked. My husband and I always tend to over-prepare for vacations- literally, this condo has everything you could want from beach towels to shampoo-not to mention a fully stocked kitchen. Travel light! I forgot to bring my magnifying mirror that I use to put on makeup. Imagine my surprise when my sons told me there was one in their bathroom! Also, my sons made me take a moment the night before leaving to go down and lie on the lounge chairs to look at the stars-I highly recommend it! Can not wait to return.

Relaxation & Great Times & Fantastic Location!!!

Everything was simply wonderful! The Condo is just beautiful with all the comforts of home, the grounds are very nicely maintained and I can't say enough about our Host, Michael, he is beyond a phenomenal Host. You can tell he really cares that you have a good stay and goes above and beyond to make sure he can help you have it! He contacted us prior to leaving for vacation, offering many suggestions and giving very helpful insight for our day trips, checking in on us after we arrived to ensure all was going well with our stay and when he found out we had a sizeable delay the day of our departure he had even more suggested stops on our way to the airport! The location of the condo is really perfect... located about half way between Key Largo and Key West it allowed for day trips in both directions. We don't travel like this much so this was a big vacation for all of us, my husband and two kids 18 & 22...We couldn't have asked for a better place to stay!! The private beach was by far the nicest we saw during our stay! Peaceful & Relaxing - and the pool was always clean and welcoming as well. Planning on a return trip!

Beyond Awesome

We loved everything about our stay at this awesome condo in Key Colony Beach! The location is ideal, it is close to several fabulous restaurants and attractions yet it is in a very quiet area. Its central location in the Florida keys made it very convenient and easy to visit Key Largo, Marathon, Islamorada and Key West during our week-long stay. The condo has its own private beach with soft, white sand and beautiful clear water. We enjoyed sitting on the balcony watching lots of boats pass by from the inlet nearby (Vaca Cut). At the end of the street (about a 3 minute walk) is Sunset Park. We walked there every evening to watch the amazing sunsets. The condo is beautifully decorated, super clean and well-appointed. . .even beach towels are provided! Communication with the owner, Michael, was phenomenal. He provided clear and easy check-in instructions and called to make sure we had everything we needed. I had mentioned to him before our trip that my husband enjoyed sleeping to the sound of an electric fan. Michael made sure a box fan was waiting for us upon check-in. He also provided great recommendations for area restaurants and attractions. This is our favorite beach vacation rental of all time. Our teenage son has already asked "When can we go back?"
