We didn't meet Sofia but were wonderfully looked after by Kalliopi, her mother, who made sure everything worked, who gave us bread and rolls she had baked herself in her oven in the street outside, and who was always welcoming and friendly. The apartment is small, and traditional. The bed is comfortable. But most of all, for anyone who is interested in a genuine experience of old-time Greece, a visit to Olympos is a must, and there can't be anyone nicer to stay with than Kalliopi. Finally, the hiking in the north of Karpathos, to Avlona and Tristomo, and above all down along the west coast back to Diafani from Aghia Ekaterina, is spectacular.
