Giorgia is an excellent host! She answered us right when we messaged her, morning or night. She also sent someone to check the stove less than five minutes after we asked her. She was also prompt in communicating before we arrived in Venice, while we were planning our trip.
The issues we had were not to do with her personally. The apartment was a little cold and one neighbor immediately started complaining about us making noise, when we weren't even out of the elevator yet. We hadn't even gotten into the apartment. There were also many hours during the day and night when we had to be quiet because of families in the building, so we would stay out of the apartment as long as possible. But the apartment is nice and if you don't normally stay inside most of the day (which you shouldn't when you're traveling anyway) I would recommend this apartment.
