the apartment was spacious and bright. Our flight was late, but we let Tone know, and there was no problem. the apartment had everything we needed; 10 or 15 minutes to 2 different Metro stations, and 15 minutes to walk downtown, and to the Lakes northwest of city center. Both the Botanical Garden and the Rosenborg castle are within sight, 3 and 5 minutes; these are must-see sites in Copenhagen; the Little Mermaid is 30 minutes' walk, and the touristy Nyhavn district is 12 minutes.
The apartment is on the 3rd floor, using the European system (4th for Americans), 50 steps. Good exercise, especially with a suitcase; just a caution: try not to forget anything when going out to avoid an extra 50 steps.
