Monica's Flat in Venice was absolutely wonderful. We were there in September when the town was flooded with tourists, so we spent quite a lot of time in the flat. As the restaurants were all crowded, we would often buy lunch and eat in the roof top dining room. The view was like a dream, and better than any restaurant imaginable.
Dorsoduro is a fantastic area, just a 15 min walk from San Marco. Just far enough to be away from the crowds, but close enough to walk everywhere.
Monica was a wonderful host. She was very communicative and flexible as our flight landed early, and we left very early.
I would definitely recommend this flat.
