This is really a wonderful place :) Cinzia was a superb host, she's welcoming, warm and fun to talk to, and also an amazing lady whom you'll like instantly once you meet her. I wished we had more time to get to know her.
On the place, Cinzia lives in a beautiful mansion full of history and has its own private bridge, with a nice view outside, and gondola passing by occasionally. The location is ideal, quite close to Rialto bridge and Piazza San Marco, but out from the touristy area, not so crowded, which is great! You'll have plenty of chances to get lost, yet won't stray too far, which I think is good if you're visiting Venice for the first time :) Cinzia also provides a personal food guide which was really very helpful and handy when you don't know where to start haha.
I would definitely stay with Cinzia again when I go back to Venice!
