The apartment is cozy, clean, well equipped, and in a great location. It is close to everything, good restaurants and bars nearby, but in the mean time it is a quiet neighborhood. We were with two teenagers and a 4 years old kid and it was good for all ages which is not an easy feat to achieve.
Maria and Carlo was very good hosts, helping us a lot with logistics (booking water taxi, etc.) and gave good advices to enjoy Venice.
I would highly recommend this aparment for everyone.
