This place is ideally located to start exploring Copenhagen. It's a beautiful apartment, spacious and very welcoming. Marianne gives plenty of suggestions to explore both the neighbourhood and the city. What is really cool is that both busses and harbour taxi (boat) stop very close to the home, so you can be in Copenhagen in no time (and if you take the boat, you get the view for free with it).
We stayed there with 3 kids and the apartment was ideal: clean and well-equipped.
