The place was excellent. It was huge and offered me a private area to stay. I had a separate entrance, bathroom and laundry area (which I didn't use but might be convenient if I had a longer trip). The house was bright and unique and like I said very private. I didn't need to see Mark at all if I didn't want to but when I met him he was a great guy so we sent a bit of time together. Mark is super friendly and knowledgable about the city. He is an artistic and intelligent guy and a phenomenal host. I would strongly recommend staying at his place if you are ever in San Francisco.
