The apartment is in a great location, just a few steps away from Piazza San Marco - you can actually see the Campanile from the flat. This makes exploring Venice much easier as you can always pop back into the flat to drop/pick up things in between visits or just to rest.
The flat itself is clean, well maintained. and spacious. The only downside of being so central is that there might be some noise on the street, and that church bells ring at night.
Communication with the host was efficient. Our train had a 2.5h delay, and the co-host Loredana was happy to accommodate our late arrival.
Overall a nice apartment to stay in one of the best locations in Venice!
