We spent a wonderful week in Venice, the flat is as per the description, spacious, well equipped and at the center of the city, we could go to anywhere by walking or just take the Vaporetto (the station is very close).
If you wonder about Francesca, I can just say that she is a tremendously helpful host. I could experience it when we were in big trouble during the last day of our stay, as we had to re-arrange our travel to go back home , Francesca was breathlessly making calls to find a solution for us and she found it !
Thank you so much for your welcome and your kindness !
