We had a great stay at Nefelia's place.
Apart from her being a very sweet person the house was great. It is absolutely something different than other airbnb places in Athens. Very artistic and it has a great vibe. Besides that the location is awesome. It is exactly in between Gkazi and Thissio. Both great locations to go out for food and drinks. A very lively neighborhood close-by with proper with silence in the house. A serious recommendation!
