A cheap and practical option to visit Venice but make sure to sleep in a private room, not in the "dormitory". The dormitory is a small room for 4 people (men and women are mixed) and no door, quite difficult to sleep there. Some fees are just ridiculous, like 10 euros per day to use the kitchen, whereas you can have a good pizza for 8 euros in a restaurant. If you are aware of this it will be fine.
