Stefano's place is a great place to stay in Venice. I had the single room with private ensuite bathroom and it was excellent for one person.
5 minute walk in either direction to the Rialto Bridge or St Mark's Square. Stefano kept in touch and checking in was easy when I arrived later at night.
My bed was made every day I came back from sightseeing, so that was a nice pleasant surprise.
The room is however, right next to the main door and the other bathroom and the walls aren't soundproof so there might be people leaving in the mornings or showering at night and you'll hear that. It didn't bother me at all but just something to note.
