As others have indicated, Federica is a well-prepared, friendly, and informative host. Her early instructions made it very easy to find the apartment - I would recommend the water taxi if you want a quick view of the island and easy walk. Federica gave me recommendations, a map, and guidelines for my visit. I definitely wish I had stayed longer!
The apartment is in a great location. Just off the main tourist area, it's very quiet but only a few minutes walk back to Piazzi di San Marco. Great for exploring Venice without being stuck in all the shopping directly.
I've already sent her listing to a friend as a recommendation, so you should stay as well
