With a group of friends I stayed in a four person room, equipped with two bunk beds, a en-suite shower and toilet.
The hostel is bery big and run quite professionally, so it lacks character. That is compensated by the good facilities, cleanliness and central location in Cologne.
Only thing I missed was at least some basic soap in the bathrooms, but other than that the hostel is a very good choice for the budget minded traveller, with a decent free breakfast as bonus.
