Look at how clean those streets are! Is there someone from Oslo who can comment on these streets now? Are they still as clean (because they're in the political district?) or did we make our cities more dirty since then?
A lot of the photos were taken around the parliament buildings, the royal palace, and the national theatre, which may explain why the streets are so clean and the standard of attire is so high.
Notable buildings in the shots are Stortinget (Parlament), the University of Oslo and in one of the shots, the Royal Castle
Background: I'm not in Oslo but I'm living in Gothenburg which is both close by (roughly 3 hours with bus) and roughly the same size. I live on the main Avenue (avenyn) walk to and from work so I see much of the central inner city every day.
