The tram stop is right outside the door. Cologne fair/ city center / Dom can be reached within 18 minutes / 8 minutes / 16 minutes and the main station in 16 minutes. Right in front of the apartment there are modern restaurants, bars and coffeehouses. This part of the city is currently the hippest and most favorite area for locals (Berlin flair). A late arrival is not a problem. There is also cinema, art/streetart, 3D mini golf and much more nearby. I can also give tips for Cologne.
