The manager is very friendly and always available. She picked us up at the bus station when we arrived and drop us off again the last day (freely!). Our room was small but comfortable and well-decorated. Breakfast was copious and variated: fruits, bread, greek yaourt, honey, cheese, orange juice, coffee,etc. The hotel is between Fira and Firostefani and you have a bus stop 5 minutes walking from the hotel to go anywhere in the island (included Oia).
The swimmimg-pool is very small. Very noisy at night, people partying next door, but the reception closes at 21h so there's no way to complain...
