The apartment is in a great location and the neighbourhood is very central. Campo Santa Marina and Campo Santa Maria Formosa is just around the corner and has several great spots for eating and drinking (try Bar All' Orologio on the latter). There's also a small supermarket on Campo Santa Marina. A short walk away on Calle Testa (nr 6369A) there is a small bakery. Getting to Piazza San Marco is about 10 minutes and to Fondamente Nove (good links to other islands such as Murano, Burano and Lido) about 15 minutes. We were 4 people and our stay was very comfortable.
Elide was very helpful with directions and answering questions and she always responded quickly (before we arrived and during our stay). She and her husband even helped by holding our luggage on departure day as our flight was quite late on the day. I would not hesitate to stay here again and am happy to recommend it.
