I would recommend Paolo's place. It was very convenient to all of the sites, and his assistant Sylvia was very attentive to our needs throughout our stay. We had one small issue with the toilette when we arrived, but Sylvia was quick to resolve the issue and even followed up the following day via text to be sure we were still doing good. Check-in was also easy as Sylvia met us near where we got off of the Water Taxi and walked us to the apartment. She then gave us lots of suggestions for things to do, and supplied us with even more info that Paolo had prepared for our stay, including maps and more suggestions for things to do, places to eat, ATM & Grocery locations, and other items of interest. We were able to really enjoy Venice because our place was very quiet, secure and so centrally located. Close enough to everything, but still very much the old-world Venice that we wanted to experience.
