Massimo is an outstanding host! He walked us to a fantastic restaurant nearby and made sure we got a table. He took us on a boat tour (for a fee) of Venice, and could not have been more pleasant and accommodating.
Sadly, his flat has some issues. The air conditioning did not work so we had to leave the windows open and we all received visits from hungry mosquitos. His building is also under construction so there was a fair amount of noise in the morning.
The flat itself is huge and beautiful, but the furniture was quite worn, one bedroom has no door and the main bath door would not close.
The location of the flat is a blessing and a hindrance. It is about an 8-10 walk from a busier street so it was very neighborhoody, but getting to St. Marks and the train station require a long walk or a water taxi-Venice is quite large.
I was also annoyed to be charged a 20 euro cash fee when I arrived, which his helper described as a city tax. If that is true, it should be listed on AirBnb and not a hidden, surprise cost payable before you get your keys.
Overall though, if you want a large flat in a more quiet part of Venice, don’t mind long walks and a hidden fee, have easy to carry luggage, don’t need a/c and can manage the door issues, Massimo’s flat is for you.
