The apartment is located at the third floor (counting the ground floor as first floor) of a 4-storey building in Oslo's trendy area of Grünerlokka (by the way, you can find just behind the corner an area with nice tiny wooden houses that reminded me of Astrid Lindgren's illustrated Pippi Langstrømpe books). The surroundings are very quiet, and there was no noise at all in the building. There are good bus and tram connections as well. The apartment is furnished in a stylish Scandinavian style, in the bedrooms and in the kitchen heating can be independently adjusted to one's needs through electric radiators, and the bathroom is all the time warm with floor heating. The kitchen has everything one needs, including a coffee grinder and elegant dishware. The owner replied immediately to all the questions I had. Highly recommended!
