We are happy to let you know we have over 40+ parking spaces in our San Francisco location, which is great for a centrally located hostel!
That said during the summer we do get very busy and can't guarantee parking spaces as they are first come first serve. Even if we do run out of space we do make it easy for you to drop off your luggage, we have two dedicated check-in/out bays to help with moving your luggage from your car to your room.
