excellent and rare catch!! Perfect location, nice bar (LAMM) next door XD, wonderful cafe P-Berg, and the whole atmosphere of Schönhauser Allee. The room with balcony is very calm (courtyard) and has everything you need, as well as the kitchen and the bathroom. The apt is suitable for those, who have to work within the days in Berlin (!).
Check-in and checkout are flexible, so you don't have to worry about it.
And Damur was very kind and supportive, that made the stay wonderful.
