I would book this air bnb again. It was clean and quiet, and the mattresses were comfortable (more firm than soft). I liked how it was a little tucked away from the business of the city, but still a very short walk to the main strip and walkable to all the main sights. Right by a grocery store and wine store. Check in was simple and host let us drop off our bags before check in which was very helpful.
There were a few things that weren't expected, which may or may not matter to you. For example, there was no shampoo/conditioner and the pillows were thin & lumpy. Communication was a little unpredictable; the host was quick to provide basic apartment details but did not respond to a couple of my questions. There was some confusion about the location as well, as when we searched the phrase we were instructed to in search in GMaps it sent us to a location 10 minutes away from the unit, which took a half-hour or so to figure out without cell service. I would now recommend confirming the location on a map with any host in Venice, and ask for landmarks.
