In a good location, easy to get places by walking (and somewhat quieter of a neighborhood which was nice for Venice). The bathroom was small but maybe that's par for the city?
Had adequate windows which was good; was a little damp/musty but maybe that's everywhere in Venice? There was a heater in our room which helped a lot!
Our host was not there during our stay but made checking in very smooth, we shared the flat with a charming French couple who were very familiar with Venice and quite helpful - good roommates :).
Overall a fine apartment but maybe not a great value for the price? I say that without much knowledge of other lodgings in Venice. I would recommend to a friend if they asked.
