The apartment is conveniently located very close to Piazza San Marco (read: near vaporetto stops, main attractions, and lots of tourists / foot traffic). There was a bit of snag during the check-in and wifi-connectivity issues, but the host(s) are responsive and the issues ultimately resolved. I came to Venice for the biennale, and the place is about 15-20 minute walk away from the Giardini and Arsenale venues.
