One attic with king size bed. One room with a king size bed and private terrace. One single room. Plus can offer a camping crib for 1 infant. The rooms share the upstairs bathroom.
If you are traveling with friends I can also offer a couch and an inflatable queen bed.
The house is 5 minutes from the train station (the train will take you to Venice in 20 minutes). Down the street from the supermarket and close to the town center but in a quiet neighbourhood on a dead-end street.
