The caldera and sunset views at this hotel are absolutely AMAZING, the staff is very helpful and kind, and the rooms are decent. The hotel makes your stay extra special by providing free wine and special snacks once a day. I was overall very happy with my 3 night stay in early October, and only had a few issues which prevent me from providing a perfect rating (I give this hotel 4 out of 5).
I booked a honeymoon suite with private jacuzzi in early October. The water in the jacuzzi was consistently room temperature and I had to call for service three times to make the water warmer. It didn't really get much warner and was never really the temperature you would expect a jacuzzi to be. Since it was early October and a bit windy, the water felt too cold to enjoy at sunset and after sunset.
From the moment I checked in, I was told that the spa was completely booked for the duration of my stay and I would have to go to Fira if I wanted spa services. This was a disappointment and I would expect hotels to prioritize spa availability for their guests.
The shampoo, conditioner, and blowdryer in the room were of very cheap quality (old school blowdryers similar to what you get in motels in the US).
Finally, there was a stray cat hanging out on the porch of my room which made me uncomfortable while using the jacuzzi, something that is very hard to control in Greece because there are stray cats everywhere but a bit of a disappointment to my overall experience.
