Lars and Sine have been very available before and during our trip to Copenhagen. The house is very big, we were a group of 7 (included a couple) and had plenty of space, and a room for each. it is situated at about 25 min from the city center, and has a direct connection to the airport by metroline. The neighbourhood is nice and calm.
I really recommend Lars and Sine's house, especially if your a family with kids.
