Our stay at numa was just perfect. It's by far the cleanest and tidiest hotel we've stayed in. The staff is always available for questions and concerns, and they deal with everything right away. The location in Schoeneberg is not the most central, but the fact that numa is located on Nollendorfplatz, which connects the whole city, solves this completely. Overall, amazing experience. Oh, and the bed is firm and super comfy!
