Zhou's Bed&Breakfast is an excellent option if you want to go to Venice, not spending a lot but staying somewhere nice.
The neighbourhood is OK, not great but just perfectly located a couple of meters away from the bus (that will take you straight to Venice in 15 minutes) or a three minute walk to the train station.
Zhou was great, she waited for me even though my train was late and understood. Every morning she makes sure you got everything you need for your breakfast and is very kind.
The room I stayed in wasn't like the one in the picture though, it was another one (bigger, with an extra bed but not as nice as the one in the picture) - which was OK but would have liked to know in advance.
Everything was clean and nice, shower worked perfectly and had an air-conditioner that really helped!
