I fell in love with Giana's Air bnb place. It is a large one room studio, wchoc was immaculately clean. The bathroom was quite spacious for European standards.
I will divide my review in Pros and Cons.
Pros: Location, location....! Very close to bustling St. Marc's square but tucked away from main thoroughfare, so quite quiet.Immaculately clean. Most importantly, open the windows and you will see gondolas go past your room. Gianna was a gracious host and met us at the Rialto water-bus stop to guide us to her place. Kitchen was small but useful for small meals like breakfast. There is a grocery store nearby. Don't forget to try the hand made pasta place just outside the main gate. Excellent!
Cons: I cannot think of any cons. Contrary to popular notion, the gondoliers do not sing when they row by.
