This is called the "Brooklyn of Stockholm" which is just bullshit. But it is an up and coming area where a lot of young people choose to live because they choose to not afford an apartment in the city. This means there will be a lot of cool poor kids hanging out here because it's close to home. But there are a few gems out here and you should visit Vinterviken in Aspudden(closeby but I don't want my map to be that zoomed out so just google it).
Midsommarkransen, Hägersten-Liljeholmen, Stockholm, Sweden
