I and my wife spent two nights at this magic place. The combination of an art studio and a flat is charming, the art pieces amazing and the guys really nice people.
The flat itself is perfectly located in San Marco. The room was super cozy and clean with a beautiful view of one of the little bridges and the bed was comfy. In the night we shared a bottle of wine and talked politics and all the other nonsense :-) We can more than recommend staying at this place, especially if you want to experience the original airbnb idea, not the nowadays capitalist version.
