Circus

Whatever else a hostel has to offer, it's always going to be the option of a free drink that draws many guests to its door. Okay, this isn't a permanent freebie, but Circus hostel generally opens a large keg on Mondays, and guests are welcome to sample the contents. More practical matters include a city centre location, easy access to public transport for exploring the rest of Berlin, wi-fi, 24 hour reception, and what is possibly Germany's largest and longest lasting breakfast buffet.
