The apartment is great, spacious and comfortable with great decor, features, and balconies overlooking the the campo below. Location is ideal if you want to be right in the centre of the city, a minute's walk through the calle opposite and you're on the Riva degli Schiavoni and Piazza San Marco. Plenty of decent bars and restaurants nearby, including one of my favourites Trattoria Alla Rivetta.
Although I quite liked the idea of being amidst the bustle of a busy square, the bar below was playing some pretty terrible music the evenings I was there, and because of the limited soundproofing the noise and the constant bass was quite annoying. Elena did try to remonstrate with them so at least the music got shut off at midnight but if you want peace and quiet in the evenings maybe double check.
