Charlotte's place is right at the heart of Copenhagen, 2 minutes walk from a subway station that runs direct to the airport. It's in a quiet street right next to a great square with shops and cafes. Close to both the waterfront and gardens and the university. Location was perfect for us.
They bought us freshly baked bread from around the corner and Danish jam and butter for when we arrived. Instructions and checkin were easy and communication was instant.
The apartment is very cozy (I think they call it Hygge). It's the 4th (top) floor of the building. We did have to carry our bags up the stairs. Not a big deal overall. Bed was an actual king sized bed (not EU king size) and was very comfortable. Shower had good water pressure and no problem with hot and cold.
Wifi was fast and we could easily work and do zoom calls from the apartment.
Overall we loved our stay. Copenhagen is beautiful and this apartment was a great spot to experience it from.
