Fantastic place in a fun location. Charlotte met us when we arrived (quite late) and could not have been more helpful and gracious. She carried my massive bag up the stairs for me, can't thank her enough for that. The third person in our group arrived two days later, unfortunately her bag didn't arrive when she did. None of us speak German so Charlotte stepped in to save the day. The layout of the apartment is great. There are doors to both the bedroom and living room so we were able to feel like we weren't in each others space all the time. I'll definitely stay here again when I return to Berlin. Also, the doner place directly next to the Kottbusser Tor station is exceptional!
