We had 4 days at Rikke's apartment in October. It was very conveniently located, about 3 minutes walk from the metro and a bus stop. The 6A Bus, that takes you into the centre of Copenhagen and all the sights, leaves regularly from that bus stop. And the metro line that passes through the nearest stop is the one to and from the Airport - making it very easy to get to the apartment. The metro runs 24 hours a day.
The apartment is quaint, in what appears to be a safe neighbourhood.
Rikke was very easy to communicate with and very helpful.
There are 4 flights of stairs up to the top floor apartment - Rikke mentions this in her description but it is important to note if you find stairs difficult to manage.
