Very simple place, but great value for the price. The room has a chair, a table, a rack to hang clothes, and a spring mattress on the floor. I had no issues sleeping on it at all but I'm not a picky sleeper.
The location is great. In a very hip part of town, right next to the U-Bahn that will take you anywhere you need to go.
Of course it's not as nice as a hotel, but great compared to a hostel and for a similar price.
