If you need a good rest at night and you don't wanna pay a lot, this place is a very good choice. The room is small, but OK, we even had air conditioning and plenty of satellite channels to watch before going to sleep. At the time being, we had really quiet and clean neighbors, nothing disturbed our stay.
Venice is just a 10-minute bus ride away, you should take bus Nr. 5. or 19. - bus ticket costs 1.30 Euros. Bus drivers are jerks, so be careful where and when you get on/off the buses..
All in all, i would recommend Primavera Hotel to all Venice travellers!
