I stayed at Katja's place during the marathon weekend and it was everything I needed to relax and get ready for the big run. A short walk to a tram stop. Then another shot commute to the Alexander Platz Station, from there just a few stops to the main station in Berlin. All in a few minutes. Very easy even for someone like me who’s not used to using trams and metros. The room is comfortable and the apartment is exquisitely decorated. I had a nice chat with Katja about her travels and the places she’s lived in. Great stay!
