Cristina's apartment was everything as advertised.
Great location on the Grand Canal and far enough from the hubs of activity to be quiet at night.
The accomodation was accessible from the Santo Spiritu vaparetto (highly recommended stop). The Billa grocery store was within 15 minutes walk (just past the Zaterre) if you need to stock the refrigerator.
Working with Cristina is very straighforward and our communication was timely. I would recommend AirBnB and Cristina's apartment for value and location in Venice.
