Maria’s place is close to the central train station. So easy to get to. Also, near the vaporetto, so a great location for me. It’s on a very narrow street, and in general it is quiet, but does get foot traffic. I was staying there when it was cold so the windows were closed and the place was very warm And cozy. That said, if you’re there in the warm months and the windows are wide open, you will hear street noise below. The loudest thing in Venice seems to be peoples rolling luggage. If you are sensitive to noise, like I am, when you sleep, this might be an issue, that said with windows closed I slept very well. Otherwise, the place was exactly as Maria described, and perfect for me.
