We only stayed one night at Gianni's place since our flight back to Paris was cancelled and despite the fact that Gianni is a very nice and helpful person our stay was not so good - I am sorry. The problem is that the room is on the second floor of a building facing a huge boulevard : very noisy during the whole night. So I think the place is a bit expensive for the comfort/location/shared space compared to the other place we rented during our stay (whole apartment in Trastevere with a great view and in a quiet location).
