What a fantastic place !
A very nice, recently renovated, traditional greek building in a very quiet area. There is a 200 sqm terrace, with an undisturbed view straight out to the Aegean, which is about 150 meters away. A perfect place if you want to calm down, read books, meditate, escape tourism & hectic civilisation.
You can reach the house easily from Gavrion port in about 5 minutes of walking. It is probably some 30 meters above sea level; no need to rent a car.
There is a supernice coffehouse not too far away which can be heard a bit, but is not disturbing.
In 5 minutes walking, you can reach Andros Holiday Hotel, which has a very good restaurant and beautiful views. Our recommendation for breakfast is EYTYXIA located in Gavrion harbour. There are fairly good food stores in the harbor.
I would strongly recommend this place for people looking for a quiet, original greek place. We enjoyed hiking on some of the official routes, which are well-signed. See http://www.androsroutes.gr/ for details.
When travelling to Andros ( from Zurich via Athens ) we stayed in Rafina, Hotel Avra, see http://www.hotelavra.gr . That worked out really nice and we would recommend it.
We plan to come back.
Thanks to a supernice host and all the useful tips he gave us.
