Sara and Lia are the most wonderful hosts ever! They will explain you everything in detail when you arrive, and be available at any hour to answer your questions!
The only thing that you have to know is that the apartment is outside from the center of Venezia. You have to take a bus during 20min to go there. But it wasn't a problem: there's a but every 20min, plus the neighbourhood is really calm, a supermarket is close to the apartment, and the apartment itself is really lovely! To sum up: you have everything you need there.
We would definitely stay there again!
