Our family of five had a very good time in Venice. We stayed in Salvatore's apartment for 3 nights. It was extremely spacious, clean, and comfortable -- especially because it had air conditioning at a time when Venice was very hot. The Airbnb listing pictures are accurate.
The apartment has two bedrooms, each with a double/queen bed. Comfortable enough. Salvatore also set up a 3rd single bed in one of the bedrooms, so that all three of our kids could sleep there, leaving us the living room and kitchen in the evenings after they went to bed.
As a host, Salvatore was very welcoming and helpful. He met us at the train station on our way in and guided us through the maze of streets to the apartment, and on the way out, he guided us back. He had cold drinks in the refrigerator, too.
The location is good -- very near the St. Frari church and other interesting sights to see. It's a bit of a walk to any of the bridges, but not too far from a vaporetto stop on the Grand Canal. We found a grocery store about 5 minutes walk away.
I would definitely stay here again if we come back to Venice.
