We had an 8 bed room and it was huge, bright, clean and the beds were really comfortable. There was a big table in the middle of the room, great for predrinks fun [and dumping makeup etc!]. Bit of a random location but I don't know Berlin at all, we just wandered in any direction and found restaurants and bars etc. Definately the nicest hostel i've stayed in, and the cheapest place i've ever stayed. I have been recommending it to all! But i am seeing bad reviews here so maybe i just got lucky!

In my eurotrip so far covering 8 cities this was the worst hostel.
The toilet is like a river with water all over
There is noise All the time (puberty kids running all over the place)
Our key card suddenly stopped working several times
The room is so hot because there is a lock on the window. In order to get off the lock every room member has to sign a paper. Wtf!? German mentality at its best?

This was my second stay and if your travelling with freinds and want to stay in a great area of the city this is a good option. It's really clean, of course it's basic, it's a hostel, however has a good bar, good staff, very close to a train station with great links so thoroughly recommend this hostel.

We spent just one night in the A&O in Friedrichshain in Berlin. The room and the attached bathroom were clean, beds were comfortable. Furniture and interior were basic but in a good condition. The room was quiet spacious. Reception staff was helpful. Although the hostel was fully booked there was only little noise at night. The location in Friedrichshain is nice if you want to spend some time in the lively and hip quarter of Berlin. Also famous Kreuzberg is not far away. You will find easy access to public transport that takes you everywhere (about 30 minutes to Alexanderplatz).
