The place is very well reachable from the train/bus station (circa 20min walking). The room was very clean and nice with its own entrance. It's divided from the rest of the owners house only by a tiny door that was closed. The own entrance is great especially when you get back very late and you don't want to disturb anyone. There is little kinda garden at the entrance to the room. It is shared with the owners entrance.
The host was very nice and even let us leave our luggage there for the whole day after check out, so we didn't have to pay any extra at the luggage storage.
I didn't have any problem with the communication. I would really recommend this place; considering that Venice is very expensive this is a great place for what you pay.
