The property is beautiful with gardened grounds and water views all around the property. Spa was small but nicely appointed with an outdoor enclosed hot tub exclusive to the spa, a sauna and access to the indoor pool. The service and massage were excellent with a lot of options to choose from. The outdoor pool overlooks a stunning bay. The area had food and drink service, a hot tub and an adult only lounge space. My young son had a blast in the pool! We stayed in a 4th floor room at the front of the hotel with lovely water views. Latitudes the restaurant overlooking the bay was good but our service was slow. The breakfast was well worth it! We had a voucher for the buffet but we chose to skip it and applied the $41 value to order from the menu. Portsmouth is close by so I would recommend grabbing dinner off campus. We also traveled to North Hampton State Beach which was not too busy and had great waves - it's a surfers destination. Overall great visit - our first and we'll be back!

Location: Portsmouth, York, ME - The island of Newcastle - which is where this hotel is located - is quiet and secluded, but just a few miles from everything.
This grande dame hotel is very pretty, and the restaurant, Salt, is divine. Pools are nice; grounds are immaculate.

Nice oceanfront facility

The only issues we had was the room was not made up one of the days. A call to the front desk immediately resolved the issue. Notices the smoke detector in the room emitted two bright white light flashes every few seconds which might be annoying to some at night with the lights turned of during sleeping. Otherwise a very nice room.

Perfect romantic getaway

Pros: The hotel, originally built over 125 years ago, has a very unique atmosphere and history, which only added to the getaway atmosphere we wanted.
Location: It is a seaside hotel located near Portsmouth NH. Only minutes from downtown Portsmouth, just slightly further from Kittery ME.
Took my girlfriend here for a romantic getaway the weekend after Valentine's Day. The hotel is far enough away from the city to give an isolated feel to it, while only being 10 minutes away from the downtown area. We found the staff to be very friendly and helpful. The room had a great view overlooking the water, which the minor snowstorm did little to diminish. We did not partake of the spa services, but after talking to several people who had, we plan to during our next visit when the weather warms up. I would recommend eating at least one meal at the restaurant, the food was quite good, if you plan on doing so, make a reservation as soon as you know when, as seating was limited. All in all we had a great time, and look forward to using more of what the hotel offers during the warmer weather.
