Cristiana's place was absolutely brilliant. It was a perfect size for two of us, great that we were able to cook there (especially as it's so close to the Rialto market for fresh produce) and it's in a fantastic location very close to everywhere you might like to visit in Venice and to a Vaporetto stop.
Cristiana was very very helpful and gave us suggestions of restaurants etc, as well as kindly letting us keep our baggage at her house on arrival and before departure, as we were getting the night train both times so arrived early and left late.
We would thoroughly recommend Cristiana's place.
