I visited Copenhagen with to friends for a weekend and we had a great time. Lines place is just wonderful. It was very clean and is so lovely decorated! We were also happy, that Line was excellently reached by telephone.
One small hint: If you want to sleep on the couch, you better be shorter than 1,60 m, but then it is really comfy.
It is very quiet area, what is really nice, and we went by foot into the city in about 20 minutes. There are also supermarkets very close.
If we ever need again a place to stay in Copenhagen, we would love to come back!
