We had a nice time staying at Fabios place. Davide welcomed us warmly and Fabio kept in touch while we stayed in Venice. There are some nice and affordable restaurants just a few minutes from the flat, supermarkets and a bus that takes you to Venice in 15-20 minutes.
Luckily the flat has air conditioning in the kitchen and a fan in the bedroom - saved us during a few very hot days in Venice. It's quite loud and noisy at the mainstreet, so we had to sleep with closed windows at night. The mattress is very soft, we had to get used to that aswell.
I would recommend Fabios flat if you want to stay in an authentic neighborhood, away from the crowded city of Venice. You can buy a day ticket or more for the bus and waterbus, there's actually no need to stay in the city center overnight. Big bonus: free parking spots right outside the door!!
