Don't hesitate: book this appartment! The location is awesome to visit Venice and the neighbourhood is lovely.
Maurizio and Matteo are available at any time in case you need them. The flat has everything you need.
We tried a few of their recommendations for dinner and it was great.
They were lovely enough to allow an early check in and late check out so that we could leave our luggage in the appartement.
Only one advice, in Venice, beware of the mosquitoes. ^^
