Gianni’s place was a great location. About a 25-30 minute walk to Saint Mark’s and the Doge’s Palace, but in a more local area that gives you a chance to escape the tourist crowd (and prices.) It’s very close to a vaparetto, which you can take to Murano and Burano.
Gianni was helpful, providing clear directions to the space (which is helpful in the maze of Venice.) He was also very responsive. Great option for Venice.
