The room offers a great degree of privacy & autonomy, as it has a private entrance which is not shared by the host.
The whole place seems like a kind of a hostel, rather than a private home.

Venice is close & easily accessible by bus.

The "breakfast" is rather poor, and consists mainly of dry food.

The neighborhood feels somewhat unsafe, though it may be a subjective thing.

Overall, the place will fit independent persons who want to visit Venice, and can take care of themselves.
I wouldn't recommend it to single girls.
