Marco had a great place for my gf and I to stay in. It was in Mestre, which is outside of Venice, but only a 15 minute bus ride, which isn't bad at all! The bed was comfortable, the sheets were clean, and the whole apartment was clean. There are markets and stores around for you to buy stuff. There's an electric shop right next door if you need to buy any converters for your electronics.
Marco was very prompt with answering our messages through airbnb and although we didn't have the pleasure of meeting him, we met his friend Antonio and he was very nice and helpful. Marco organized for us to be picked up and dropped off again at the airport by Tonino (very nice man!) and that was for 25 euros each way.
The ONLY negative thing I had to say about it was that I felt limited in my showers because the shower would fill up with water so you had to do everything before it started to leak on the floor.
Other than that I would definitely recommend this place for stay!
