My stay at Hara's Houses was wonderful! Exactly as described. Stamos was reliable and friendly, the studio was cozy and well equipped. The bed was very comfortable and the view is unbeatable! It is a short walk to Fira (15-20 minutes) or a quick taxi or bus ride. There is a place to rent cars and motorbikes just up the hill, a little market and several restaurants. I highly recommend Anogi and the Aegean.
The only improvement I would suggest is to provide nicer coffee for the mornings, for us coffee lovers. There is a french press but only nescafe packets provided. I loved my time here, though, and would happily stay again!
