We loved Sergio's place. He was very accommodating and met us at the Vaporetto stop so we didn't get lost on the way to the apartment.
The apartment was very nice and we enjoyed our stay. We loved the porch!
Unfortunately, it rained the majoring of our stay, so we didn't get to enjoy it too much, but the views are great!
Everything in Venice is very walkable and Sergio's apartment was in a good location. Kid friendly, too! :)
