Düsseldorf’s residents call their home “the 10-minute city”, because it rarely takes longer than that to get wherever you want to go. That’s a big claim for somewhere that boasts no fewer than 50 stadtteile (mini districts), but it’s backed up by a transit system of U-Bahns and S-Bahns that gets you around easily. And therein lies Düsseldorf’s great appeal: a small city of just over 600,000 inhabitants, with the infrastructure, the internationality and the sheer cultural heft of a much larger place. Add in the fact that more than 57% of its area is green space, and you can understand why a recent study ranked it the world’s sixth best city to live.
