Mark's apartment was a perfect for my boyfriend and I. It was very clean and had everything we needed for our stay. We were not able to meet Mark however he gave clear and detailed instructions so we didn't have any problems during our stay. He also had many suggestions for things to do in the city as well as books/guides in the apartment for reading more about the city. We loved the location of this apartment. It was a short walk away from restaurants, cafe's, the grocery store, and the bus stop was right across the street. The view from the street was also wonderful. My boyfriend and I took a short walk to the top of twin peaks where you can see a perfect view of the entire city. Overall, Marks apartment made us feel so at home in San Francisco!
