My wife and I stayed at Tobia's place in early November. The apartment is a real gem in terms of location: it is very close to the Rialto bridge, the San Marco square, several Vaporetto stations, grocery stores, cafes, shops, etc. The bathroom is freshly renovated and very well equipped. There is a small kitchen with everything necessary for a short stay. WiFi works really well.
Among the minuses, I could mention a malfunctioned heating system during our stay. The room temperature was uncomfortable at night. Perhaps, arrange this question with Tobia if you arrive in late Autumn-Winter. My understanding is that the hot water is also limited, and might not be enough for 2 people.
