We had a fantastic stay at Niels' cozy apartment in the center of Copenhagen. The apartment is so close to everything! The apartment itself is very well furnished and has all the amenities one would need for a short or longer stay. We also used the couch bed that was in the living room and it was a very comfortable sleep.
Niels himself was very friendly and accomodating, and also very quick and easy to communicate with.
I can highly recommend this apartment, and will very likely book it again if I am ever in need of a place in Copenhagen.
