Luca's place is perfect, 5minutes from the 'imbarcadero' Guglie for the Airport's vaporetto, not even 10 minutes from the train station and only one bridge! :), 15 minutes walk to Fondamenta Nove for the vaporetto to Murano, Burano and Torcello, and 20 minutes walk from almost everything.
Very clean and near lot's of little bars and restaurant, Vino Vero (happy hour), Il Paradiso Perduto and Il Timon (restaurants) and Torrefazione Cannaregio (coffee)!
Sure recommendation!
