Roberto's place is delightful. V comfortable with modern kitchen and bathroom. Very near Fundamenta Nove which is a great ferry hub for all of Venice, but it is so close to everything that you can walk to all sites. Out of tourist noise and bustle, near supermarket,restaurants and bars.
Great little shop for fine Marino wool jumpers nearby - if you can find it!
Would recommend a stay here if you have a few days in Venice.
