Nana's house is amazing. It's not exactly in the city center but is really close to there (1 km). Mini markets and cafes in a walking distance. It's very peaceful, cozy, brand new (renovated) and charmy. You fell you're home and living like a local, in the middle of a Santorini neighborhood. We were very well received by Nana and her son Elias, meeting us in the nearest parking lot, helping us with the luggage and receiving us with fruits and cold beers. Fantastic reception and fantastic house. 100% recommended.
