Airbnb could create a new category or a new level of host: the "hiperhost" or "the megahost", because that what Mark is. I was lucky to arrive at the same time of the other guest, so Mark picked us up in the airport. Also he made a rooftop dinner for us, he cooked delicious breakfasts and he always was telling me stories and histories about San Francisco. He also provided a lot of suggestions about bars and places to go - he is very updated about the city.
The room is great, the kitchen is great, the building is great... so that's why he can be much more than a simple superhost!
