The apartment is exactly as it appears in the photos: modern and well furnished with attention to the details; air-conditioning and flat TV in every room; very beautiful bathroom with a big shower.
Every day the staff does the cleaning of the apartment and changes all the towels (also the bed sheets if it's necessary).
The unique discomfort for us was that it's forbidden to throw any kind of paper in the toilet, so there is a small trash bin for that in the bathroom. Anyway this problem is common with most of the places in Santorini.
Giannis is very kind and helpful: he oganized for us a private transfer for the airport and he welcomed us with fresh fruit and fresh water. Giannis' family has a motorbike rental shop next to the apartment, so it's possible to rent there (at a good price) a scooter/quad for moving around the island.
The apartment is sited in a very quiet zone, exactly in the middle between the beaches and the main city (Fira). Not far from there (400 meters) there are a good bakery, a supermarket open everyday until midnight, some restaurants and other shops.
