I really enjoyed being on a calm island with beach and a terrace next to Venice. It takes 25-35 Min with the waterboat depending where you go to in Venice or start from and is like a sightseeing tour every time.
The room is as described and very clean. I didn’t meet Mariella but a man who showed me the apartment. We ended up on the terraces talking 2 hours about Italian culture. Those are the experiences that make airbnb so nice. You get a lot for the price, try it :)
