First and foremost, if you have mobility issues, this may not be the apartment for you. As other reviewers may have mentioned, there are four flights of stairs and they are quite narrow. It was not an issue for us, but future travelers be warned.
The location by far is the best reason to stay here. We stayed for ten days and everything was close by, including Norreport Station, multiple bus lines, Stroget (very walkable street), and Torvehallerne market. All the major tourist sites were within walking distance and we had no issues getting around. If I were visiting Copenhagen again, I would stay here.
