This is the single best AirBnB I and my wife have yet discovered. We suspect it might be the best in Venice, and perhaps much further afield than that.
What made it really perfect for us was that a) we wanted to be away from the tourist crowds and b) we wanted somewhere convenient for the Biennale hubs at Arsenal and Giardini. Giovanna's place is 3 minutes' walk from both of those!
But the quality of the design, decor and furnishings, in contemporary style and with great attention to detail, makes it an outstanding property in its own account. And the people-focus and human quality of the welcome from Giovanna and her family support team was most touching. We felt we were in a home from home - which in a city as touristy as Venice is a huge achievement.
No hesitation at all in recommending this apartment for a couple, for any length of stay (the longer the better!). Just do your best to deserve it!
