We chose Ca' Bongiorno as our base to discover Venice and that turned out to be an excellent choice for our family with two little kids. Elisa & Stefano's flat is literally 3 minutes from a bus stop that has a frequent and direct route to Piazzale Roma of Venice, which is as far as you can go into Venice on wheels. You can also purchase Venezia Unica day passes nearby in tabaccherias, valid for both the bus and the vaporettos. The apartment itself was very well equipped, clean and surprisingly quiet for the central location. Parking was a non-issue, we always found a free spot a few steps away. For groceries, there's a Coop some 3-4 minutes walk away and a Lidl farther. Stefano was very helpful and prompt when we needed a little help. You can't go wrong with choosing to stay here.
