I would definitely recommend staying at this hostel. It's a beautiful building and inexpensive, friendly staff, the bar is open 24 hours, laundry service, computers, lounge areas, luggage storage and you can rent locks for the lockers in your bedroom and a hairdryer if needed. It's at a great location with easy access to U and S-bahn stations, you can walk to Berghain and other dance clubs like Tresor, Arena, Chalet, etc. Highly recommend! I enjoyed my stay here and also made a few new friends.
