Marks place is accurate to the photos he shows. Even though the place is just big enough to hold 1-2 people at he same time, must likely to be a family.
We had a situation with the cleaning and the linens when we got to the apartment that Mark actually took care of it right away. Other details like the shade or curtains that were stained didn't help us on feeling the complete clean of the unit. The hallway leading to the apartment is really sketchy. For our previous experience in other AIRBNBs with the details, locations and extra efforts of the hosts to make you feel at home. We felt after staying at Mark's that the price for this listing is high.
Other than that we enjoyed the location and our stay in SFO
