I loved the apartment, the location and the neighborhood!
Everything in the house is lovely: it's clean, warm and very well furnished.
The apartment can be reached very conveniently from the airport, since it takes less than 30 mins by train. You can arrive at Carlsberg station, which is 2 mins far by walk from the apartment.
To go to the city center, you can just walk thru Vesterbrogade/Istedgade/Sonder Blvd or take Metro 3 from Enghave Plads (4 stops and you're in Nyhavn).
Carlsberg is a lovely neighborhood, where you can find many locals and few tourists ;-). I highly recommend Cadence and Bageriet Brod for breakfast, while Bulko and Ramen To Biiru for dinner.
Christine has been a lovely host, always helpful when we needed some advices. I definitely recommend her location!
