Me and my friend stayed in a six mixed-room. The room was alright, quite clean, nothing special with it. The shower and toilet was okey. The wall was literally outside the hostel. The U-bahn and S-bahn is very close to the hostel, just a few minutes walk. Most off the staff was kind and helpful and could speak good English. The hostel is like ryanair; it's very cheap but you have to pay extra for everything else, like wifi in your room, play pool, bedclothes or borrow the computer. It can be quite noisy with the traffic if your room has a window but it shouldn't be a problem if you aren't bothered by it.
