Giovanni was an excellent host. We were only in Venice for a short time and he made excellent suggestions as to what to do in so short a time. His suggestions proved spot on!
The flat itself is wonderfully situated, close to the Rialto Bridge. It is very basic, small, but clean. I wouldn't recommend it for a prolonged stay, especially with more than one person. Also, the climb to the forth floor would be a challenge for the less able and those laden with luggage.
