The room I stayed in was a mixed sex space which I was not aware of before I arrived. However, the other tenants were very polite and courteous so there was no conflict at all. The hostel itself is not glamorous nor does it have any particular frills but, it was a quiet, safe place to shower and sleep after a long day of adventuring- I do appreciate that the bed was pretty comfortable. Overall, now that I know what to expect, I would stay here again as it was more affordable than other options in San Francisco proper.
