Overall, a very pleasant experience. Alessandro received us at the vaporetto stop and took us back to the house. As we had arrived a bit earlier, he kindly let us keep our luggage in his shop until check-in time. He then gave us an excellent overview of places to visit, where to eat, how to get around, etc. He was an excellent host.
The apartment was great, very neatly kept and maintained. The location was good for touring the city, just a few minutes from St. Mark's square. It is overlooking a somewhat busy street so it can get a bit noisy until late evening. But then again, who would want to sleep early in Venice anyways?
