This is great place to stay, easy to get to from the airport and into the centre of Copenhagen (several buses going to different places, it takes about 30 minutes to get inot the centre). We were 3 adults so Marie put a full-size mattress in the children's room which worked fine. The main double bed is in the living room (with a large wardrobe screening it off) which worked fine for us. Nice bakery nearby and everything we needed was in the flat. The flat is in a quiet location, very well equipped & very comfortable.
Marie was very helpful before we arrived and came around very quickly when we had a minor problem on arrival (the cleaner had forgotten to put out towels).
