Panos' place was exactly as described - beautiful views out east over a vineyard and the sea, immaculate, modern, clean room with air conditioning and a refrigerator.
It is well within walking distance to Fira and Firostefani (I'm glad we stayed somewhere that allowed us to take that walk - absolutely beautiful!) as well as being on the famous hiking trail between Fira and Oia. The Villa was very close to the famous Skaros Rock hike, and also to a handful of restaurants, shops, and car hire/excursion planning places where we booked a sailing tour.
This is a wonderful family-run apart-hotel, with a real touch of Greek hospitality. Panos' father served us breakfast every morning and even gave us a ride to our next hotel for half the price of a taxi! Can't fault the place at all, and the rate was very reasonable indeed.
I would absolutely stay here again!
