What a great location and neat apartment! Check-in was a breeze. We really appreciated having coffee in the apartment every morning and access to a washer and dryer. Coming and going to airport was breeze due to quick walk to the Metro and everywhere else in Copenhagen was accessible with a lovely walk. We especially liked being so close to the outdoor beer garden and street food across the pedestrian/bike bridge from Nyhavn.
As others have mentioned, it does get noisy when the bars let out around 3AM.
