Stefania met us at the vaporetto stop (which is right beside the apartment) which was very kind. Her apartment is lovely, with lots of space and a GREAT view across the canal to St. Marks. Cruise ships passing right by the window was very cool too.
Only thing to note is that apparently the heat doesn't get turned on until October 15th, a city bylaw or something. We came in mid September and had a few chilly nights, but extra blankets were provided.
All in all, would stay at Stefania's apartment again in a heartbeat.
