We have just experienced 2 enjoyable days in Frederiksberg, Copenhagen. The apartment is very spacious and comfortable as depicted on the website - and well worth the walk up 4 flights of stairs. It is ideally located within close walking distance to cafes, restaurants and the city.
Charlotte is a very helpful and welcoming host and passed on a wealth of local information. I would have no hesitation in recommending this accommodation to those planning a visit to Copenhagen.
