Köln may not be the exact geographical center of the European Union, but it sure feels like it when you are one of the one million inhabitants living in the Rhine-metropolis. While the locals may talk about the importance of living on one side of the river or the other, it actually does not matter – whether you are trying to get around Köln or planning a trip out of town, everything you need is within easy reach of the city center: subways, autobahns, the main train station and the international airport.
