The pools have lovely beds surrounding them. The restaurant and bar areas are great. The bar offers views overlooking the sea. Breakfast is spot on. There is a great selection at the buffet with a lovely variety of cuisine. It was fantastic. I found the staff lovely.. they are always smiley and attentive.
I found very little shade around the pool area. There are parasols, but they are a bit small.

The staff was attentive.. they promptly addressed all requests. The room was spacious and well-equipped. Breakfast offered great variety, with many options.
The gym was rather small. It only had a few pieces of equipment. The walk to the beach involved a somewhat busy road. This lacked a dedicated pedestrian path.

pool shadeawkward ladder
I was a bit disappointed . I found there to be very little shade available around the pool. this made it difficult to relax comfortably during the day. the restaurant prices also seemed a bit high for the portion sizes i received! i think they need more umbrellas. also, the access to the larger pool was awkward with just a two step ladder, i struggled to get out.

Some Issues at This Hotel
uncomfortable bedbroken sunbeds
My stay wasn't the best. I found a few things that could be better. The room had furniture I didn't like, and the bed was really uncomfortable and I did not sleep well at all. finding a sunbed by the pool was a task and some of the beds was broken.
