Location is excellent, local bus to Fira and local tour company is nearby, hotel breakfast was excellent & has good selection, housekeeping clean & change towels everyday, although they don't dust the dresser & night stands, but overall room are very comfortable, air conditioning works well.
Note: taxi do not use meters & even though they do, they will still charge you at a flat Eur15-, which is ok'sh to compare of waiting to the airport bus which is not too reliable. Mineral waters are very cheap all around Santorini.
Kamari tour company provides excellent & efficient guide if you happen to go for a day tour, highly recommend the Bus & Boat day trip, it's worth it at Eur 36-/pax.
