A really great place to stay in Copenhagen. It takes 2 minutes by foot to get to the Metro station (which has a direct line to and from the airport - a ride that takes less than 15 minutes). From the apartment to city center it takes only 5-10 minutes by Metro or by bus. There's also a supermarket and a 7/11 store that are very close to the apartment (1 minute walk).
The apartment is great for a couple and is cozy, warm and very clean. Although Rikke was abroad while we were there, she met us at the airport and was very friendly and helpful.
P. S
For those who are interested, Christiania is 5 minutes by foot
