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.

Hotel has the best sunset views in Santorini. Our room had its own plunge pool, you can watch the sunset from our pool. The hotel only has a breakfast option but no restaurant Inside the hotel. There’s plenty of dining options close by though. Be prepared to walk though as obviously no cars can come to this area. They sent a staff member to help us bring our luggage from main road, it’s about a 15 minute walk. Highly recommend the hotel amazing views and quieter than other parts of Santorini.

This is a beautiful hotel for sunset views and romantic evenings spent at the pool. Staff was very helpful, organized, and polite. I recommend getting the room service breakfasts, everything was delicious. The path of stairs that leads you to the hotel from where your driver will be able to drop you is long and can be tricky to walk up and down due to the slippery stones so bear that in mind when booking. I was able to do them while five months pregnant but probably wouldn’t be able to in the third trimester.

This property is in a good location, right in the middle of Oia. Be prepared to walk the steps though because it truly is in the middle and there is no direct access to it. It looks over the sunset and down at Amoudi Bay which is nice. I will say, the staff is not very friendly or welcoming. The rooms are pretty average, cracks in the floors, stained bathrooms, etc. The private hot tub on our balcony was very cold and the view was very obstructed. We asked about heating up the hot tub and they pretty much said that there was nothing they could do about it. Overall I was very underwhelmed and would not stay here again.

Very unique hotel and experience but i don't think I will ever stay there again. I booked the hotel as i didn't want to fight with other vacationers for a view of the sunset. Have mixed feelings here. While it has one of the best sunset views there isn't much the hotel has to offer other than a picturesque pool. Couple things you should know before booking this property: 1) the exact location of the hotel as you can't it on google map. I did a lot of research on the hotel before i went there so found it easily, 2) if you are goiing back to your hotel few times a day then beware of the stairs as the hotel is maybe 1/3 its way towards the pier. Going down is hard enough, going back up is like a full workout. 3) While the room itself is very unique it is quite small. There is not much sitting area in the room too. The bedroom is on the 2nd level and the spiral staircase is the tiniest i have ever seen. I can't imagine how a tall or big guy can climb up the spiral stairs. 4) hotel does not have any other facility I am not saying that this is a bad hotel, had a great time there. Just that I find it hard to justify staying there again and pay a premium when there isn't much they offer.
