In my opinion as somebody who has travelled and stayed in many hotels over 40 years in business this hotel should not be rated 5 Star it is at best a 3-4 star The hotel is very clean with great staff who try very hard to please the guests The position of the hotel is misleading as from pictures on Expedia it’s appears to be on the beach it is positioned one street back from the beach looking over an older hotel The pictures on the beach show sunbeds that belong to the hotel but are situated in front of a bar that serves drinks on behalf on the hotel The pool at the hotel is very small and cramped with no space between sunbeds As a plus the breakfast buffet was very good and the rooms are well appointed My overall feeling is a hotel that has great staff offering an out standing service but lacks the facilities and position to be considered 5 star

Lovely boutique hotel! Would stay again, the food was good and the hotel was brand new. We stayed on the suites side which I recommend.
