Where to begin. It is filthy, not charming. The shower is a hazard, not small. The heaters hardly ever work. The hot plate worked once in three days. The rugs are stained and stink. There is no place to wash dishes except the shower. The view is the house across the street, 10 feet away. Their view is your bed. Better used as a hostel room for about $20.
A better suggestion is to stay on one of the lagoon islands where you can actually see daylight. Even better idea, skip Venice and the hordes and go to Lake Iseo. Much better.
