We loved Copenhagen. It's a very good location in the historic centrum of Copenhagen, and we found it quite silent for such a central location (only some passage in the morning for the hotel, but no noise during the night since it has a closed entry and is located at the back of the building). Very clean sleeping room, bathroom, sheets and towels. No curtains indeed, but that wasn't a problem, since it got dark at 4 pm and we had 2 comfortable beds. Friendly and correct hosts. Enjoy your stay.
