My wife and I stayed in Carl's apartment for 6 nights and it was a wonderful experience. Carl and his wife were very considerate to allow us an early check-in around 11 am and provided many useful local tips. The apartment is very quiet, clean and convenient (very close to Metro station and there are three very good bakeries, etc.). The kitchen is very well equipped and it was very nice to prepare simple meals out there (given there are so many organic things in Copenhagen). I would strongly recommend this apartment to whoever wishes to have a pleasant Copenhagen holiday.
