The apartment is very nice, comfortable, and clean. What we did not like is the way to enter the flat: we were three and had only one key. The main door (from the street) is not possible to open without a key or tag, and the same as to enter the building and apartment. So it was necessary always to agree between us when who and when is coming or leaving the place.
Another thing which we did not like was that all the closets were full of the owner's things, we couldn't put our things in. And, there was no coffee machine...
Although I wrote what we did not like, I would emphasize that it was very pleasant to stay in this apartment, Rune is a nice and helpful person and if we come again to Copenhagen, we would ask him to book the place.
