Location is very central and the apartment is quite nice. Check-in instructions can be slightly confusing if you have not stayed there before, with different codes for different doors, entry into the courtyard from a different address etc. but once you sort it out you will be fine. The location is on Vestergade, one of Copenhagen's busiest party streets, but generally there is not much noise spilling into the building as the apartments all appear to face a courtyard. Mind you there is a steep and narrow flight of stairs up to the apartments, which might be a bit of a hassle if you have loads of luggage, a stroller, etc.
