We had a great stay at Andreas's apartment. It is in a fabulous location right next to a major train station, food markets, and coffee shops. It is also within walking distance to many sights to see in Copenhagen. The apartment was very clean and had all the amenities that we could ask for. I had only 2 minor complaints, which may not actually bother others.
The first is that the closets were completely full along with every single drawer, and even every coat hook. The reasons I like AirBnb is to unpack and feel like I have a home away from home, so the frustration of tripping over our exploded suitcases and nowhere to put anything certainly took away from our overall experience and made it feel more like we were crashing at a friend's place.
The second was that the apartment is on a very busy/noisy street, which is what makes it so conveniently located. It had very good windows that kept most of the noise out when closed. Unfortunately it was too hot to sleep with the windows closed since it was on the 3rd floor with no fan, so it was a bit noisy throughout the night, especially on Friday and Saturday night.
