Carstens apartment was perfect for our stay in Copenhagen. Check-in was easy - you just have to be aware that the key is further away from the train station than the apartment, but it was no problem at all. The location was wonderful - kind of in the center city but yet quiet and calm. You are in three minutes at a central place of Copenhagen's shopping street. Right around the corner there are great spots for coffee or dining and the canal is also right around the corner. The apartment itself is cute and has everything that you need. We appreciated the stay a lot and we definitely recommend Carstens apartment.
