I wish we could've stayed longer. Beautiful view, clean room, quiet, and very friendly staff. And yes, you have to meet Wilma.

"This place and staff were AMAZING"

10.0

Can not say enough about the staff from the market and the (Buffalo) butcher to the restaurant and lounge. Who can’t say enough about the office staff. Extra hugs to Oli for making Annie the happiest. Miss all already.

"Perfect Place"

10.0

This is a wonderful combination of bougie and relaxing. It’s perfectly nestled in the calm waters with an excellent beach space. The two pools are great; one is adults only and a perfect place to relax. Top that with three different food and beverage options and the best staff I have ever met; this place is a gem.

"Beautiful Stay"

10.0

Absolutely stunning stay. The oceanfront views are unbeatable—palm trees, calm blue water, and a peaceful, relaxing atmosphere. The pool area is beautiful, clean, and just steps from the beach. The room was spacious, spotless, and thoughtfully decorated with comfortable beds and a private balcony perfect for morning coffee or sunsets. Everything felt well-maintained and intentional. We would absolutely stay here again and highly recommend it for a serene beachfront getaway. ⭐️⭐️⭐️⭐️⭐️

We were so thrilled with this beautiful, family owned boutique hotel and can't wait to return. The cocktails and food at the restaurant felt Michelin-worthy, the views and pools were lovely, we slept like a dream and the welcoy felt like we were VIPs.

Dimensione della camera è tranquillità. Staff gentile.

La parte “spiaggia” inesistente con poche sdraio e mucchi di sabbia pronti da spianare…
