We had a very pleasant stay at the Villa Malvolti. Francesco and Marianna were friendly and made us feel welcome all time. The house itself is a piece of art! In the nighttime the Malvolti Villa had a little ghosty touch, but that's how old big houses are. ;)
Without car you're in five minutes at the train station, which brings you to Venezia in like 20 minutes.
All in all we can recommend it.
