This is a great place that is quiet and no kids. You do have to climb stairs to get to or go from the hotel but the perfect place to watch the sunset night. People come from the island to where the hotel is to watch the sunsets. The staff was amazing and very helpful. One of the better places we have stayed

Had an amazing experience with the hotel overall , I loved how it was in the quieter part of oía and felt more peaceful. The staff and service were amazing and rooms were comfortable and clean. The breakfast here was so good i highly recommended to purchase. Just be prepared for cliffs and steps because they are all over the island. But we would stay here again for sure.

Awesome stay and an amazing place to watch the sunset. We stayed in a suite with a hot tub overlooking the water, which was wonderful. Surprisingly quiet at night given how close all the hotels are to one another. The front desk staff (Thanos) was so welcoming and lovely and even let us drop our bags off early in the day. Only thing that bothered us is that the air conditioning did not seem to bring the temp in the room to a comfortable level. It was a bit hot and stuffy

Location and view of the sunset are spectacular. However we booked the honeymoon suite room and upon entering, the room is nothing like the photos that’s presented online. Every room you see on the website all have a view of the sunset and a jacuzzi. Wish we didn’t spend the extra price for a room with small windows looking at the ocean. Would recommend to stay here but don’t spend a heavy price on rooms.

The hotel only gets 4 stars due to the hill to get to the property. It is why the hotel is quiet and has a great view of the sunset, but the hill is also very steep and difficult to navigate in spots.

The best thing of this property is that you're right in front of the best sunset you'll ever see. Then the staff is super friendly and accommodating. I will book here again.. but make sure you bring clothes you can wear with comfortable shoes because there are a lot of stair to go up and down from the hotel's location.
