We loved Riccardo’s place - it was in a pretty area with not so many tourists, yet of course close to everything since Venice is so compact. Riccardo is an excellent host, very quick to respond to questions, flexible with check in and check out, and providing all kinds of local tips.
There is a very popular bar downstairs which means noisy at night, but we read about this in other reviews, packed earplugs and had no issue with this whatsoever. Quite the opposite - it was lovely to see locals having drinks and friendly chats at night.
Definitely recommended.
