This Nord Collection apartment is really worth its price.
The room has high-quality furniture, all amenities you need (you can do laundry, cook an easy meal, etc.) and the bed and bathroom are very comfortable. The apartment is in a quiet neighbourhood, but very close to Amager Strand (beach) and a 6-minute walk to Lergravsparken Metro station, from where you are in the city centre under 10 minutes and at the airport in 15 minutes.
Another important aspect is the very good communication with Nord Collection. They won't bother you when you don't want to be, but if you have questions or if there's something that needs to be solved they respond very fast, are highly friendly and help you wherever they can.
I would certainly recommend the apartment if you're visiting Copenhagen alone or as a couple, both for work or on holiday!
