Mark's place was amazing! I was traveling to SF for work for the first time in 2 years, so naturally I was apprehensive. Mark made me feel right at home in his penthouse apartment. The location is very convenient (though a bit on the gritty side), but Mark was very conscientious about checking in and being available to ensure a smooth and safe check-in process. He was easy to reach and responded promptly at any time of the day. His apartment was extremely comfortable and clean, better than any hotel I could have gotten. If I'm traveling again to SF, I'll definitely we be staying with Mark again!
