This apartment is a perfect place to stay in Copenhagen. It's a quick walk to everything you could possibly want to do in Indre By -- Tivoli, Nyhavn, Christianshavn, Kongens Have. The only time we used the Metro was to and from the airport. The Kongens Nytorv station is super close, and the train goes right to the airport.
Communication was fantastic, including detailed instructions and tips of things to do nearby. Carsten arranged to have the key available for pickup from a safebox, which was really convenient.
The apartment is clean, comfortable, and well appointed. Thankfully, the shower includes a curtain so the entire room does not get wet. The bed is sizable (queen?) and comfortable. The bedroom and bath look onto an inner courtyard, which was very quiet. It got pretty warm during one of our days there (30C/87F); and it was great to be able to open the windows in the evening to get a good cross breeze going, which cooled everything nicely.
We highly recommend this apartment and will definitely stay here again!
