First - the location is excellent. Very close to the subway, not far from a grocery, possibility to park in an fenced area next to the house (this is not trivial in Copenhagen).
The host was friendly and she gave us the keys exactly as agreed.
Then, of course, there are things that could be better. The apartment would be perfect if you come just for one night without any luggage. But if you want to stay for a week, then you might appreciate some place for your clothes and all the stuff you carry in your luggage but you do not want to keep it there all the time: infortunately, all the cabinets and closets were full of the host's stuff to the last cubic centimeter.
But I would recommend this place if you want to enjoy Copenhagen and want just to briefly sleep somewhere.
