Santorini is absolutely beautiful. Old Castle is an affordable option and was just as described. We loved and used the outdoor pool/jacuzzi that was part of our room. Additionally, the hotel had a pool where we spent one day relaxing. The hotel’s location on the caldera is breath-taking and you can watch the sunset from your room/pool area. However, that means you need to walk a bit more to access the hotel - not a big deal if you are young, but we watched some middle-aged/older couples struggle with the extra steps to the hotel.
The view from the hôtel is breathtaking it was a amazing !!! Just be ready to climb a lot of stairs you need to be in shape!

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
The property is famous for its pool overlooking the sea and the best place to watch the sunset. We also had a private pool and area that we could enjoy out of the eyes of other tourist. Staff hotel were extremely accommodating and helpful. We would love to come back to this place
Excellent location. Best view of the sunset in all of Santorini. Excellent reception staff.
Giorgos was very hospitable and friendly. Answered our questions, made reservations for us and always with a smile. 10/10
This place is amazing!! Best views in town! Staff was unbelievably friendly & helpful. Made you feel right at home. I can’t say enough good about this experience. There’s not one thing I’d change.
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.

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.
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.
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.
