Great place to stay in Venice, I would highly recommend staying here. It is very comfortable, with views of the canal from one of the bedrooms and kitchen. The upstairs rooms have windows on the roof that can be opened, which brought in cool air at night.
We had plenty of space for our 5 kids to sleep, and the living area was large enough for us to feel comfortable. The apartment is only about 10 minutes away (walking) from the Rialto Bridge/Grand Canal. There were also a few restaurants close to the apartment that we enjoyed eating at.
