This place is ideally located to visit Venice. Right near the train, bus, etc. That being said, it is a very small place, seems like a storage unit converted to a room.
The twin beds cannot be connected, instead there is a sofa which can be opened to accommodate a couple, however it is not very comfortable and when opened takes up the entire room.
Cooking is not really an option, if you were counting on it.
Also, there is a water heater in the room which comes on and off during the night- so not great for light sleepers.
There is no screen on the window, so it must be closed to avoid the mosquitoes.
Bare in mind an additional charge of 4euro/person/night - city tax.
Other than all those flaws, it is a great location, Stefano and his wife are very nice and accommodating.
