My husband and I have stayed at a lot of different Airbnbs in Berlin, and Stefan's apartment is among the best. It's extremely well located near Rosenthaler Platz, has a lovely balcony, an unusually comfortable bed, and plenty of space. As a host, Stefan was very accommodating. There are a lot of great bars and restaurants nearby and great access to various public transit options (and the U-8 subway line is very well connected). As a bonus, there's a supermarket almost across the street in case you want to keep some food/coffee/wine on hand.
