Mark is an incredible human being and a wonderful host. His condo is just as it appears in the photos: well lit, clean, tasteful, and comfortable. I stayed in the master bedroom with the private bath and it was a home away from home. Mark is extremely respectful of his guests' privacy, but at the same time makes them feel at home and invites them to participate in his social life (hosting dinners for friends, rooftop barbecues, etc.) so that they don't feel like they're a formal guest. The fridge and kitchen are well stocked and you'll definitely leave healthier than when you walked in! I can't think of a better long-term stay in San Francisco.
