i loved the direct access to one of europe's best beaches i have seen plus the staff kept everything in top shape and the lunch menu offered diverse choices i also enjoyed the comfy sunbeds and pretty sea views overall it created a wonderful experience. my suite featured a private pool i enjoyed and it was so nice. the hotel also held an outdoor movie night.
the mosquito problem impacted outdoor enjoyment after sunset i wish the hotel provided mosquito repellent measures like candles to improve the outdoor environment in the evenings . it would make outdoor activities better.

The beach had excellent staff. It also featured a great lunch menu plus lovely sunbeds. The rooms are spacious with modern bathrooms. Many rooms include good outside space, especially the rooftop rooms. The spa provided great service. My partner and I each enjoyed a message from the great team.
Mosquitoes presented a massive issue. The hotel does very little to mitigate this. Sitting outside after sunset became unenjoyable.
