The flat was great. The location is quiet and away from noise. There is a grocery store within walking distance to stock up on the necessities for your stay. Several restaurants and bars nearby as well.
Everything on the description is accurate. Massimo is a great host and accommodating. He even let us drop off our luggages early. They were still getting the flat ready by the time we got there at around 11am, so it wasn't available for check in yet.
He offered to pick us up from the airport, but we had to decline because of our party size. However, he offered to take us to the train station when we were departing Venice. Highly recommended.
