We had an amazing stay at Cliffhouse and were pleasantly surprised by how beautiful it is. The only minor issues we encountered were that the pullout couch was quite uncomfortable for our kids, and it was frustrating that children aren’t allowed in the main pool—everyone with kids ends up crowded around a small pool off to the side. Aside from that, everything else was fantastic!

Wonderful stay overall! My husband and I came up for a family reunion and greatly enjoyed the property and loved revisiting old stomping grounds. There was a tiny bit of confusion with the access codes as it was noted we were on the fourth floor in the email but we figured out quickly it was really the third floor. Smooth sailing from there and the condo was beautiful, clean and loved the amenities! Highly recommend and we looking forward to coming back soon!
