Rebecca is a wonderful host! I wound up getting sick while I was in Berlin and wound up spending an entire day laying around the apartment. Though this Airbnb is more geared to those who would like basic amenities and to spend most of their time exploring the city, Rebecca helped nurse me back to health with lemon tea and medicine.
Note that the apartment is relatively no-frills. The proximity to the metro station is a huge convenience, but you can hear trains throughout the night so make sure you're a heavy sleeper who can handle a stiffer mattress. Rebecca's hospitality, the centrality of the home, and the awesome decor are strong highlights.
