It can be loud long into the night/morning on the weekends, but you are literally right smack dab in the middle of it all. It is a 3 minute walk to the Kongens Nytorv metro station. Nyhavn is a quick walk away and the best bakery is just across the street.
Mathiaes is an amazing host with very quick response to any questions.
You are on the top floor of a historic building. There will be tours stopping by to snap pictures.
The kitchen is quite functional and coffee/tea supplies are available. You are able to cook if you would like.
There is a washer AND dryer in the apartment.
I would definitely recommend this place to anyone wanting to visit Copenhagen.
