We had a wonderful, if too-short, stay at Ninni's flat. The location is excellent--it's in CPH's most multicultural neighborhood, on a quiet street, and just steps from the neighborhood's largest greenspace (which doubles as a historic cemetery). It's not far from the city center, either by foot or many options for buses. The flat itself is lovely, clean, and quite comfortable for two people. The wifi was strong and the host was very helpful. Can't recommend highly enough!
