We spent 4 nights in Valeria's place while in Venice. It was a very convenient home base for us. It was quite easy to navigate to from the bus or train station and Valeria's friend Anna was very helpful greeting us and welcoming us to Venice.
The nearby Campo Santa Margherita square was great; very lively and plenty of options for food or drink. We really liked that this was tucked away from the more touristy parts of Venice.
The only downside of our stay was the heat. The flat is not air conditioned, which I suspect is very common (and we knew when we booked) in Venice. The fan helped but it was pretty warm at night.
