Very nice place to stay for a small family with a 4 year old child. The apartment is inside a quiet neighborhood, with plenty of light. The bathroom seems recently refurbished and the kitchen is in good condition. The bedrooms are also nice, with natural light in all of them.
The location is also great. 10 minutes walking to the train station, close to the vivid area of Ponte delle Guglie and close to two ferry terminals, which came in handy when we visited Murano. There is also a couple of restaurants very close by, ideals for an evening rest.
I only have one comment about the apartment and is the bathroom smell. Although it was not a deal breaker, it wasn't nice either. I understand is a common problem in the area.
One final observation are the stairs. There are three including one inside, and although for us they weren't a problem even with the stroller, I suppose they could be a concern for other guests.
Overall I recommend this place to stay in Venice.
