The B&B is a beautiful old house located in Marghera on the mainland near Venice. It's easy to find and there is a bus stop nearby. It takes about 15 minutes to reach Piazzale Roma by bus so it's easy to get to the island.
When we arrived we didn't meet Gianni in person but he responded very quickly to our messages and did everything he could to make sure we have a pleasant stay. The staff that we did meet was also very friendly and helpful.
The B&B itself was pretty but I would be careful if you're allergic to dust since the room we stayed in was quite dusty.
