Adriano and Barbara were the perfect hosts!
This was our 3rd Airbnb on our European vacation and it was by far the best.
The communication with Adriano was simple! He picked us up at the water taxi station and he messaged us on our second day to make sure everything was going ok.
About the apartment: they have everything you'll need from a large bathroom, clothes washer, full kitchen (which he stocked with a few goodies), high speed internet (we streamed Netflix) and an A/C (which was needed in the summer).
The location is about a 30min walk to St Marks and some of the other sites. That said, you are close to tons of shopping, restaurants, and only about a 10min walk to the train station.
Overall, I can't say enough nice things about Adriano and his place - it was perfect for our trip to Venice!
