I will start with pros - Stefano is very nice and you can communicate well with him. I could leave my luggage at the place after checking out. Also, the place is close to San Marco and Rialto.
The cons - I booked a room for one person. So the room was super small (smaller than I could have expected from the pictures). The furniture was old and stained. The radiator in the bathroom was rusty. The room was next to the bathroom used by other people and I could hear absolutely everything from the bathroom (no need for details, one can imagine).
In spite of the good location and Stefano’s very nice attitude, I would not stay there again.
