This is a fantastic place to stay when visiting Venice. The location is perfect, just a street away from the sea (river) and restaurants. Giovanna is extremely thoughtful and helpful. She sent maps and tips on accessing Venice and how to find the apartment. She greeted us on arrival and informed us of important things to know during our stay.
(As others have mentioned, take note of the Venice tax for staying on the island. You'll need to pay this on arrival.)
The apartment is the perfect size. She gifted us tea and coffee, as well as pasta and churros which we were able to cook there. On the final day she offered to leave our bags at a local restaurant to save us carrying them around all day.
Giovanna was easy to get hold of when we needed help or advice and was very useful in her suggestions. She gave us plenty of tips on what to do and what to look out for.
I would highly recommend Giovanna and her apartment as a place to stay.
