If you want to have a great time in Berlin, I don’t advice to you stay at this apartments. On photos it looks nice, but in real life it’s disgusting. Everything very dusty and dirty, bed uncomfortable, sofa won’t spread out fully and it’s unreal to sleep on it. Bed sheets also very dirty. If you’ll stay at room number 3, prepare to live right near dump. It seems like the whole neighborhood is take out trash near your windows.
