We really enjoyed staying at the Tintoretto apartment. Cannaregio is a cozy neighborhood and much less crowded than the main tourist spots. Very close to one of the nicest canals, with the nicest places for aperitif and dinner. The flat is very comfortable,the little balcony on the canal is unique, and airco is definitely a big plus when it's 34 degrees in the city.
