Mark's place is excellent in every respect. Comfortable, clean, and spacious with good facilities and a great location. More than that Mark is a great host: communicative, friendly and his enthusiasm for Venice life is infectious. The room I stayed in is on the ground floor and so separate from the rest of the house which is spread over the upper two floors, which as I had work to do was a plus for me too. I've stayed at a lot of places in Venice and in all respects Mark's place is up among the best of them.
