“Superb”
23 Jun 2025
The staff were exceptionally friendly and attentive. The food was delicious, and the beach setup was impressive. I especially appreciated the evening service—they brought water, refreshed the bed, provided clean towels, and even left a chocolate on the pillow. Breakfast, meals, and drinks were all outstanding. Overall, it was a fantastic experience, and I would absolutely return.
