Vincenzo is great and his place is also nice: really well located, clean, big room, very close to a tram stop!
I´ve been in 5 different places through airbnb with my mother and Vincenzo´s was the best one in the overall.
Even though we used to wake up very early in the morning to visit the city, when we went in the kitchen all the things we needed to have breakfast were there (even the coffee machine was with coffee)!
Was a truly airbnb experience: he provided maps and guides to us and lots of tips about the city. Also one evening that we didn´t go out (we were really tired) I had a really nice conversation with Vincenzo about food, politics, economy, etc...Couldn´t recommend it enough!
