The place is really nice, quiet and well decorated, and we would definitely recommend staying there. Unfortunately, we were there in September and if we had known, we would have chosen another month. Not because of the island or the house (not at all!), but only because of the wind. September is VERY WINDY, so we never had the chance to enjoy the patio to sit outside, for example. We did manage to go to some lovely beaches, especially the ones where you are protected from the northern wind (which, apparently always blows, especially in September), such as Levrossós in Aigiali, and Maltezi Beach. But at Chora, where we had most of our dinners, it was impossible to sit outside without a jacket. After 10 years of different places in Greece, that was a first for us ;-).
As to the host: we would have preferred meeting him in person, but we only (briefly) met his assistant, who picked us up from the port and drove us from there to Chora. So we cannot say much about him, or his wife, unfortunately.
