Very nice hostel, clean and well run. Only complaint is they charge extra for things like hanging out in the common areas if you have a late bus departure.
Best hostel out of the three that I used in SP. Clean, great staff, good breakfast with a fun bar out front yet quiet enough back in the rooms to go to sleep at 10 PM if you wanted. Highly recommend booking here if it is available.
Great hostel, my only complaint is that sometimes you get stuck waiting for too long for the employees to open the door if they have left the front desk. Minor complaint however.
