Our stay at Gianna's air bnb was wonderful! The apartment is even better than it seems in the photos. It was so lovely to have the windows open and watch the gondola's drive by. Gianna was also excellent with communication and she provided very accurate directions for how to get to the apartment (navigation in Venice is tricky).
The only minor frustration was that I missed the notes about the separate cleaning fee & taxes that were due upon arrival. This is noted in the post, but I was just looking at the total cost through air bnb. It is still definitley worth the price - just something to be aware of.
