Ca' Elena was a perfect place for us to stay, nicely located on a side canal, viewable from our windows. It was just a short walk from the Rialto Bridge and vaporetto stop.
Spotlessly clean, the bedroom was comfortable for sitting, as well as sleeping, with plenty of drawer/closet/shelf space for clothes. The kitchen was well furnished. The elevator was reliable and handy. Flowers grew in stairwell window pots.
A thoughtful convenience were a couple of electrical converters to aid guests who didn't bring enough.
We wished we'd had more time in Venice to enjoy Allegra's hospitality!
