We enjoyed our stay here. Note the fireplaces do not function!
The apartment is truly spacious, which is nice when you have multiple people around, but shows its age in some ways--the floors are very creaky (long noisy walk to the bathroom in the middle of the night), and the doors between the two front bedrooms, as well as from the bedrooms onto the living room, barely close and do not provide a barrier to any sound whatsoever. I recommend earplugs.
The best amenities are certainly the expansive, comfortable living room couches, and the heated bathroom with rain showerhead. We also enjoyed using the drip coffeemaker and having access to a washer/dryer.
Something to contemplate here is whether you are looking for an "authentic" experience in this city. This is most certainly not an apartment that a contemporary dweller of Copenhagen lives in, and that is apparent from the way that it is decorated and furnished (akin to a "staged" apartment) to the location, which is on a street that has no dwellings, just offices and businesses. Having stayed in the city before, I'm leaning away from what we found here, and toward a place that is more representative of how people live; something more cozy, personally decorated and full of life, and surrounded by other homes and apartments.
