My 13 year old son and I spent three nights in this apartment in July 2014 and had a fantastic time. The location near the Rialto Bridge is ideal for walking to many of the important sites in Venice. It is also easy to reach the apartment from the train station or airport. The hosts provide easy to follow directions (with pictures) to the apartment, which helps tremendously.
The hosts, Sara and Giovanni, live in the apartment next door. You get your own room and you share the kitchen and bathroom with whoever rents the other room. Our room was the larger of the two rooms, which was very nice for two people to be able to spread out. We didn't see our apartment-mates very often, but they were very friendly and quiet and it was nice to be able to help each other (we helped them use the washing machine, for example). From our bedroom, we couldn't hear the shower or anything else from the bathroom. We had the windows open the whole time because it was the middle of summer and it was very quiet. I did not cook in the kitchen (we were in Venice with fabulous restaurants!).
Sara and Giovanni provide a lot of information about what to do in Venice, including recommendations for restaurants. We tried one of their recommendations and we were very happy with it! They also provided us with a map, but the writing on the map was too small to be able to read the street names, so make sure that you have your own map (or buy one from a tourist shop once you get there). A good map is essential in Venice, although getting lost is part of the fun.
I highly recommend staying at this apartment. If I were to come back to Venice with only one or two other people, I would happily stay here again!
