Very nice and spacious flat. Open and very clean. Oskar is very easy to communicate with. This flat is in the heart of the city, so do be aware that there will be noise outside so if windows are open, you will hear people outside until 3-4 am. We stayed in the summer during the heat wave so windows were open all night. Also, you will need to walk about 4-5 flights of stairs to reach top floor. Oskar was kind enough to help us carry our luggage.
Otherwise, it's a great flat and we enjoyed our time there. Oskar is a great host and we would recommend his place in Copenhagen.
