We stayed for five nights in Grazia's charming apartment; so central and convenient. Grazia met us at the vaporetto stop, recommended some very nice restaurants, and directed us to the nearest supermarket and local cafes.
The flat was a comfortable haven when overwhelmed by sightseeing, with good wifi connection and everything we needed for our stay. Two minutes walk to San Marco and an easy hike everywhere else. We had a really great time in Venice, enhanced by living in a real apartment at the centre of things.
