We had a wonderful time at Nina and Niels' place. Niels was kind enough to wait up for us arriving at 1.30am, and was around again in the morning to make coffee and give tips of what we should do in Copenhagen. We arrived without anything planned but Niels' recommendations kept us busy. The apartment is in the best part of the city - near great restaurants, bars, parks and the lakes. We can't recommend this place enough!
