Mario was a wonderful host. He met us at the vaporetto stop and walked us to the apartment and showed us everything we needed to know (including the wonderful wine shop across the street - delicious wine for €2.20 per liter). He was also very responsive to the couple of questions we had during our stay. The apartment itself was great - clean, quiet, supplied with snacks. Finally, the neighborhood is perfect. Away from the bustle of the St. Marco piazza, you are still only a mere 10 minute walk away from all of the main sights (and it's a beautiful walk). We would highly recommend staying here!
