This is a very lovely place in the heart of venice. It's very close to the Rialto ferry-stop where the famous bridge is and you can take the boat to the trainstation from there. It's also 10-15 minutes walk away from the San Marco place.
The only negative thing was, that it was very hot and there was no air condition, but they provided a fan so it was a bit better.
I would totally recommend this place!
