we stayed 2 nights at Bruna's Airbnb and we can only recommend to stay there.
The room was exactly as they described and it was very clean. The flat is close to the bus station, so very easy to get to the center of Venice (15-20min).There was also a supermarket where you can buy everything you need.
The host was very helpful and friendly. She gave us some advice what we should visit in Venice, which haven't been in our tour guide.
We felt very welcome! :)
