Communication with Jenny was easy, she replied fast and gave us very detailed directions on how to reach her place. Jenny was very kind, we were allowed to do an early check in, we received a map and a lot of tips on what to visit, the best places to eat and so on. The location was great, the space clean and the bed very comfortable.
The only downside would be the fact that the walls are really thin, so we could hear both TVs of the other guests. But we only stayed one night in Venice, so it wasn't a problem for us.
I recommend staying in Jenny's place.
