My stay at this hotel was quite enjoyable, thanks to the stunning sea views and beautifully arranged communal areas. The breakfast offered a delightful variety, and I appreciated the friendly and attentive service throughout my stay. However, the room I initially received did not match the advertised standard, and the gym facilities were lacking. Overall, it was a relaxing escape, but there are areas that could use improvement.

I had a lovely time at the hotel. The stunning views from the breakfast area really made my mornings special, and the pool area was a fantastic spot to relax. However, my experience began on a rough note due to an unexpected room change which was less than ideal. Overall, it's a beautiful place, but a few hiccups marred what could have been a perfect stay.

Our stay at the hotel started off a bit rocky due to a plumbing issue, but it quickly turned into a lovely experience. The breakfast was outstanding with a fantastic variety, and the pool area was a perfect place to unwind. While the location is convenient with easy access to the beach, I found the air conditioning situation troubling and the strict morning checkout policy frustrating. Overall, it was a memorable trip, but some details definitely need improvement.
