9.2/10 Wonderful! (43 reviews)

The checkin process was super simple. They have a tablet in the unit that you use to communicate to their agents. The agents spoke English which made everything that much easier. They answer the tablet everytime and quickly. Wish they had a bathroom upstairs.

9/10 Wonderful! (154 reviews)

The hotel is situated right next to the sea and the sunsets are stunning. The room is big and quite comfortable. My only complaint is the toilet had a continuous noxious odour that may be from the backflow or exhaust of other units.
