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.

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.

We had a problem with our shower’s drain from the very first day of our stay and the property failed to take our complaints seriously. The receptionist did make an effort and put acid in the drain twice during our stay but that didn’t help. I complained every single day of our stay and as far as I know no handyman was called to look into it. The situation got so bad the last day that the water leaked from the shower into our room. Instead of finding a way to compensate for the bad experience, I was told this was the first time there was a complaint about the drain in this room - I honestly don’t know the purpose of saying that to me when there was no real action being taken by the management to fix the issue. The main pool was almost always dirty with bugs floating around. Our private infinity pool however was cleaner compared to it, still it had dust settled at the bottom. I was really looking forward to staying at this property, but overall my experience was really disappointing given the amount of money I had spent. Should have stayed at some other hotel.

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

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.

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.
