Great location in christianhavn - just opposite to the monumental church and a minute's walk to christiania, very clean and spacious house with all the amenities, Claus was a warm and helpful host.
The only concern was that the house is on the 4th floor and there's no elevator - but it's an old construction so i can imagine - ideally as a young solo traveller - i wouldn't be bothered by it, but with my parents who are 65+, i was a bit concerned. However it was easy as claus helped us with the luggage.
The house was also just a 2 min walk to the metro station... so you're just one stop away from the city centre and nyhavn.
I'd definitely book again recommend it to others.
