excellent staff great lunch menu lovely sunbeds expensive restaurant small portions missing amenities

The beach is one of the best I have been to in Europe! The staff provides excellent service. There is a great lunch menu, lovely sunbeds and beautiful sea and scenery. The rooms are excellent, spacious and modern with lovely bathrooms.

The restaurant was very expensive. Many dishes were vegan or vegetarian, and portions were small. A lot was missing in the suite for a 5-star hotel.

private beach helpful staff amazing breakfast limited menu included drinks mosquito problem

i stayed in a beautiful double room balcony sea VIEW. The breakfasts was amazing and had good variety. The beach was private and clean, with a nice bar. Staff was VERY helpful, always ready to assist with any requests.

the EVENING menu was very small and uninspired. i had the half board, but it did not include drinks, I thought this was bad. Mosquitos was a big problem.
