Sarah was quick and efficient to communicate with. She helped us with an early check in and arranged that we pick up keys from her flat mate's workplace, which was very helpful. Her apartment is also very cozy and homey. The room itself was perfect for the four of us who stayed there, and is much larger than I had originally imagined it would be. It was big enough to have space, even with three other people in the room. The kitchen was well stocked with pots/pans/utensils, but is a little small and can get cramped when others are in it. The flat itself was close to the U-8 line, which took us anywhere we needed To go. I only met Sarah for a moment, but she was kind enough to put up our laundry for us and give us advice about the town. Her flat mate, Viole, was extremely kind and spoke with us several times while we stayed at the flat. She even let us borrow her book on Berlin and try some sweets that she had brought home-- it was like sharing a house with an old friend. Overall a great Airbnb experience for the price and quality.
