One of my latest endeavors took me to Vesterbro in Copenhagen. It's right by the city center, which makes it a very popular area to live in. Vesterbro used to be notorious for prostitution and drug trafficking but the neighbourhood has cleaned up drastically over the last decade. The area was known as the worker's quarter and the local red lights district. It is now a blooming hipster paradise with trendy cafés, small corner shops selling local design  products and cute organic green grocers on every street. The architecture is mostly from the end of the 19th century, mostly working class industrial buildings that look like they're packed with so many stories and so much history that you just feel energized simply walking around among these giants (cause them building be big since they obviously had to accommodate as many workers as possible on as little area as possible). Copenhagen's own Meat Packing District is also in Vesterbro and still largely serves it's initial purpose. There are more butcher shops around  than there are meatlovers. Since it has become very hip and popular over the past years, a lot of cultural events take place in Vesterbro and many architectural firms and galleries have set up shop here. Vesterbro is just cool in a safe and comfortable way.
