We really enjoyed our stay at Pietro's apartment. We were a family of five staying two nights during August.
The location is really superb. It's 10 minutes walk from the train station and within easy reach of the main tourist sites, but outside of the really busy areas. There is a square nearby with shops and restaurants that are *much* better in terms of quality and value than on the other side of the Grand Canal.
The apartment is a good size for a family. There are two bedrooms plus a sofa-bed in the lounge. There is a seating area in the kitchen and a small outdoor terrace (which is well-shaded). Inside was clean and modern, the beds were comfortable.
Pietro sent some comprehensive instructions for check-in and we were we were met at the apartment.
