Hotel is nice but unfortunately too much construction going on at the time of stay and restaurant was closed. I would consider coming back once construction is complete. Overall, liked the location and the stunning view of the ocean.

Loved the ocean view from my room. The room was clean and staff was super friendly and helpful to all my questions. Most importantly to me was that the walls were thick or insulated enough that i couldn't hear any of the adjacent neighbors through them.

Excellent location very nice staff , our ac unit was faulty However with it only being a 2 night stay it wasn’t worth the hassle, they were extremely friendly I’m sure if I pushed the issue they would have dug into it, also was fully booked

The rooms were clean but the property is run down in a few areas. Customer service was good but one of the ladies at check didn’t appear to like her job. I don’t have her name but she was the middle aged blond lady. Everyone else was wonderful.

Correct pour le prix, bien placé + parking gratuit

Nous étions au rez-de-chaussée avec une vue sur la piscine. Le petit déjeuner, n'était pas du tout ce quoi nous nous attendions, muffin, lait au chocolat en briquette. Le café/thé devait se faire directement dans la chambre. La chambre en elle-même était correct. Mais nous étions vraiment bien placé et point bonus le parking était gratuit.
