I traveled to SF with 2 other friends, and we stayed at the Pacific Tradewinds hostel for 6 nights-- it was an absolutely wonderful experience! All staffs were extremely welcoming and down to earth people. We were given a lot of useful info regarding how to get around and also some local events. The hostel has great vibe; the people are all respectful of one another's space and very clean. If you enjoy traveling, meeting new friends, and get the best out of your SF travel experience, I'd highly recommend you to stay in this hostel.
