Best airbnb experience I've had so far. Clean and funky apartment, silent and spacious, right next to the metro. The area (Friedenau) is also very green and pretty! Han's sister helped me check in early, which I really appreciated. And when I needed to change the down pillow to a regular one, Han's sister borrowed me her own pillow. Super thoughtful and kind. Communication was also easy with both of the sisters. Definitely staying here again, if I'll ever come back to Berlin!
