Morena and Fabrizio are lovely people and great hosts. They met me at the boat and took me to the apartment. They explained everything and gave me tips about local restaurants.
I won't say much about the apartment because their description is accurate. I can add that I'm a bad sleeper and I loved that the bedroom was pitch black with the shutters closed, and that the apartment was very quiet.
Also, to avoid confusion, it's on what Americans call the third floor.
I've spent a lot of time in Venice, and this is my favorite neighborhood. Quite close to the lovely S. Maria dei Miracoli, and other interesting sites.
Although their "street" has many restaurants, it also has hardware stores - it's not just tourists. [Also it's convenient to the boat stop that's closest to the airport.]
All in all, great hosts, great apartment, great location, great trip!
