9.2/10 Wonderful! (339 reviews)
The property was lovely and the staff was very friendly and helpful! Rooms were on the smaller side but big enough and we had a sea view with a balcony which was gabulous. My favorite was the private beach which was beautiful with chairs and umbrellas without extra charge. We ate at all 3 restaurants and food was great! Only downside is it is isolated and taxis are impossible to get and expensive you definitely need to rent a car.
