You can comfortably stay in this aparment with 6 persons (if you don't mind having 3 beds in one room or sleeping in the living room). The Riaolto Bridge is 10/15min away by foot, you have nice restaurants and little bars nearby.
The view above the rooftops of Venice is beautiful and everything you need (for cooking etc.) is available. Every request is answered in a few minutes, the only thing we missed we're mosquito nets - bring some kind of insects repellent!
