Giovanni kept in regular contact with me and directed me to Rialto the best way from the airport. The apartment was clean and he had brought us a packet of Venice business biscuits which was really sweet. Giovanni provided us with a map and gave us a detailed guide to where the best restaurants were.
The apartment is very central, especially to rialto bridge. Everything is within walking distance and it took us the first day to find our bearings!
The only down side was the WiFi wasn't working which did cause us problems. This was due to the provider, not Giovanni and as we were only there for 2 nights it didn't get fixed in time. I'd definitely recommend the apartment for the location and the neighbourhood is nice and quiet.
