We stayed in an AirBnB run by Adriana just west of the Rialto Mercato and Rialto Bridge. Location was great - 2 minute walk to Rialto Mercato (including the Rialto Mercato vaporetto stop which we took to the train station), s tough to get a GPS fix in those narrow alleyways at times.

Overall, this was a great experience for AirBnB first-timers and we would recommend the location.
