Our stay in Venice was a gorgeous and breathtaking experience and the apartment was one part of that. It's really very central in a beautiful old building and directly next to the canal. You can even see it from the bedroom window. The street is a little noisy but it was okay (and usually I feel easily disturbed but I slept well). It was superbly clean, everything you need is available and the organization is more than easy. I would definitely stay here again. I felt like really living in Venice ; -).
And the trattoria is very great, you have to try it!
