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.
