Mark is one of the best hosts I've experienced with airbnb so far - he really goes out of his way to make you feel comfortable and at home. The room is spacious and lovely, and he adds a lot of little extra much appreciated touches (Ie bottles of water, a guide to the area, little snacks) and is always reachable. His home is gorgeous and the location can't be beat. I truly hope to stay here again when I am next in Venice.
