Good location, next to Kastellet (a 17th-century fortress which is now a park and an active Danish military location) and an easy walk down to the little mermaid, Nyhavn, etc. Copenhagen in general is a very compact, walkable city. Kastellet in particular is a fantastic place to walk or jog. We happened to visit during a heat wave (over 30º C) so the lack of air conditioning was unfortunate - however A/C is super rare in Scandinavia (the problem is usually keeping warm enough) so this was not a surprise. The apartment is off a courtyard, which I suppose makes up in privacy what it lacks in views. The furnishing is sparse and minimal in the Danish style - perhaps a shade too minimal, as for example there are no cabinets in the kitchen and you have to stand on a stool to reach a high shelf to get a glass. But overall the place was very nice, the beds comfortable, the self-serve check-in experience was seamless, and I would happily stay here again.
