We enjoyed our stay. Communication with the host was easy, and we only waited a few minutes to get into the apartment.
The apartment is fantastic and the location is perfect. It is large and quiet yet a five minute walk to Saint Mark's square.
My only comment is that the host does not provide some of the little touches that we have experienced at other Airbnb's. There was no water or drinks of any sort in the refrigerator or coffee in the apartment. The bathroom did not have shampoo. Etc. Great apartment but none of the little extras.
