Although we didn’t have much time to interact with our host, Mark’s place was perfect for our stay in San Francisco. It is very well decorated and furnished. It was also very cosy. The only thing I would point out is the location of the apartment: you can walk to the subway station, but the neighborhood has some homeless people and drug addicts and some areas can be very dark at night. You need to walk a couple of blocs to get to a bustling street.
