What is the main setting in the novel, The Human Flies?

25 Krebs’ Street serves as the primary setting of the novel. 25 Krebs’ Street is located in the Torshov neighborhood of Oslo, a lower-middle class area. 25 Krebs’ Street was built in the 1920s in the Torshov neighborhood, and is a simple three-story apartment building with a simple lift in the stairwell, while each bathroom has a flat. The building is owned by Anton and Randi Hensen, and contains three floors of rooms, as well as basement living quarters for the Hensens. On the night of April 4, 1968, K2 is called to 25 Kreb’s, to Room 3A where the body of Harald Olesen is found. From there, K2 begins a deliberate process of interviewing residents in their flats. The residents who live at 25 include Kristian and Karen Lund and their son; Swedish student Sara Sunqvist; wheelchair-bound Andreas Gullestad; American diplomat Darrell Williams; and an ex-Nazi named Konrad Jensen.
