We stayed here for two nights and loved it. The space is very comfortable, clean, and well equipped. The location is excellent with easy access to airport transfers and public transport stops. Plenty of restaurants and shops in the immediate area, and lots of sites within easy walking distance. Piazza San Marco is about a 10 minute walk from the apartment. The hosts are very communicative and gave several recommendations for restaurants in the city.
We would definitely stay here again next time we're in Venice!
FYI, Google Maps can be a little finicky on the precise location, so make sure to look for the specific address number above the door.
