Lovely and cosy apartment in a very quiet and gated courtyard. San Marco and Rialto well within walking distance but prepare to get lost, it's all part of the fun. We got lost as soon as we got off the water boat but Cristian found us and took us to the apartment. He showed us what's what and gave us a couple of recommendations of where to eat. He was very helpful.
Just as other reviewers have said, the bathroom is very compact but bare in mind it's a very old building. Don't let this put you off booking.
Would definitely stay there again if we return. Venice is a very beautiful city.
