First of all, communication was great and the hotel was kind enough to organize a transfer from the airport when we arrived. They also recommended a day-trip on a boat which they would have also booked for us. We ended up not booking that trip, which in hindsight was maybe not the best idea. The check-in went very smoothely as well. On the day we left we were able to store our luggage at the hotel for free and they organized a taxi for us, which took us to Thira.
Another big plus is the location. The hotel is right by Perissa beach, a very beautiful spot within walking distance of various beach bars and restaurants!
The hotel was quite nicely furnished and was clean. However, the room we rented (3 single-beds on Airbnb) was quite small and in my opinion does not look like the pictures on Airbnb.
To sum up: great location and customer service, the room could have been nicer and more spacious!
