Elena's place was very convenient for our short stay in Venice! It even had AC and a fan, which were huge sells for us. We never had too far a walk to anywhere, and the restaurants around us were yummy and cheaper than what you'll find closer to San Marco area. Only con was the bed was a little creaky, but didn't bother us much at all.
Elena was also a kind, very helpful host. She was very responsive and gave great advice for us to enjoy our stay there. I'd definitely recommend her.
