Line has a beautiful, modern and minimalistic decorated apartment. Everything was clean and towels were provided as well. We even could use the kitchen and fridge (that was actually useful). The location is cool as it is located in a hip neighborhood called norrebro. Walking into the center was fine for us too, please note that it takes around 30min from the apartment. The metro is located just around the corner which was very useful when going back to the airport. The communication with line was easy and she answered very quickly. At the last day, we could even leave our luggage there until 4.30pm in the afternoon, which was great for us.
All in all, we had a really great stay at the apartment and Copenhagen is a beautiful city with a visit!
