Massimo was one of the most friendly people I've ever known. He is open to your questions and tries to help for every need of his guests. He sent detailed information, maps before we arrived Venice. His English was fluent, clear. And he is a really knowledgeable person.
The position of the house was great, with a distance of just 5-10 minutes walk from the Rialto bridge. The house was more comfortable than seen on the pictures. One side of the house is a canal. It is not between the buildings. Massimo waits for his guests.
We stayed there for two nights. And we are sure that we will try to stay there the next time.
