we did not meet Sara, we just came in the apartment at the forth floor of a crumbling building of the old east side of Berlin. There was no lift.
The flat was all except cosy. Very small and uncomfortable bathroom, kitchen with just a couple of chairs and an old table. No pots or plates or glasses or tablecloths. We spent two days in that flat but we couldn't sleep due to the bed. In fact it wasn't a bed. They were different cushions of a sofà put together and placed on the floor. No pillow but some cushions of different size and consistency. Even the quilt was uncomfortable and short.
Just the wifi was functioning and the location was good near transportation and Ubahn not far from Alexanderplatz.
