Wonderful little place! Small, really suited for one person although a adult with a small child might work. The room was spotless and well equipped, the bed was very comfortable and there was very little noise either from inside the house or the street.
The procedure for opening and locking the door seems complacated, but is actually straight forward and easy to remember.
There is a small but private patio (no view)
The location is fabulous! Right at the foot of the Accademia Bridge which also has a water bus stop. It is easy to get anywhere in Venice from here. And there are fewer tourists in this part of town.
Downside? There is limited shopping and the few restaurants in the area are ok, but not outstanding. Both better restaurants and more shops are just across the bridge.
Also the bathroom is small. I'm 6' 2" and weight 200 lbs. I was quite comfortable, but a really big person might have a problem with the shower.
