We loved Fiorella's apartment! It was better than in the pictures. It was in a great spot near everything but in a quiet little square that had nice restaurants. Thierry her husband was easily contactable by text but we didn't meet him. I met the cleaner's husband who didn't speak English so it may help to know a bit of Italian. I would recommend the easiest way to get there on Vaporetto line 1 and get off at Giglio and follow the signs to Felice Theatre.
The apartment was clean and bigger than I was expecting for Venice. There is a supermarket about 5 minutes walk away. Very nice apartment, we wanted to stay longer!
