8.8/10 Excellent! (74 reviews)
The property is great. The location is perfect. The room was outstanding. Checkin is an absolute nightmare!!! Took us an hour from arrival to get our room. It's all done online, nobody to greet you. I saw one person in 4 days on the property. Requested fresh towels sent a text message had to send it again 8 hours later. Finally, got our towels.

8.2/10 Very good! (1,169 reviews)
Property and staff were fantastic, buffet was delicious but Linda pricy for someone who’s not eating more than the necessary.
Amenities were ok, pool is small for the amount of people at the hotel; if you lucky the beach would be clean and you can enjoy the beach. Other than that is an okay location for relaxing.
