I had a nice time in Venice.
It is well located, close to dei Frari Church and Scuola san Rocco. It is 10min walk from Railway station and bus station, very convenient for tourism around Venice (Padova, Vinvenze, etc.).
The flat is as on the pictures, in an old building but clean and functional (wifi worked perfectly). It is a bit dark, as many places in this city. The location is animated during the day but very calm in the night.
I had contact with andrea by phone, his friend Simone for check-in/out, both friendly and helpfull.
