Location is perfect : quiet by night, a short walk from groceries, next door to Fondamenta Nuove (water liaisons), easy walk access to all Venice hotspots. Moreover, I found myself loving the Cannaregio area, so typical and far less crowded than Rialto - San Marco areas. From there you can really experiment the "labyrinth-effect" produced by succession of tiny streets and water lanes.
The flat seems like providing a genuine Venezia atmosphere, and everything was right about it. We were warmly welcomed by Paola, Pietro's friend, with ponctuality and kindness. I strongly recommand this flat.
