Mark is the superhost of superhosts. If you are reading this note then I expect that Mark's place is on your shortlist. My advice would be to move it to the top of the list immediately!

I endorse all of the positive comments that have been stated already by other guests. It is an enriching life experience meeting Mark. He went out of his way to make make my stay in San Francisco as enjoyable as possible. He is an ambassador for San Francisco and to be frank, the Airbnb business model.
