My experience staying at Adriano and Barbara's apartment was one of the best I've had on AirBnB. The location was awesome, 10 mins walk to Venezia Santa Lucia station and 15 to Piazzale Roma. It is also conveniently close to a stop on the vaporetto. There are plenty of good food places around and Venice is a walking city so you'll see plenty of sights around. Adriano and Barbara were kind enough to let us store our luggage at the apartment at noon and met us at night to go over stuff about the apartment and Venice. They were easily accessible throughout our stay and they even helped book our taxi to the airport on the day of checkout. Our stay was short, but if we go back to Venice, Adriano and Barbara's will be first on our list.
Grazie!
