I grew up next to Düsseldorf. I freaking love this city. Wouldn’t it be so expensiv i would live there.
Because it is a magnet for anime fans, i early came in contact with queerness and different worldviews. Düsseldorf still has a big connection to art and due to figures like Joseph Beuys the art community is still pretty progressive. I went to university there and the campus had a progressiv Atmosphere there as well.
But on the other side the city is full of rich and conservativ people. A weird contrast. I would say Düsseldorf is educated while cologne is more open and welcoming.
