The apartment is more than large enough for 2 people. The kitchen and bathroom are very nice, clean and modern. It's very comfortable and spacious. There is a lot of counter space in the bathroom which was great. There are also plenty of mirrors so sharing a bathroom is easy. We always felt safe in the area. When we looked out the window in the middle of the night, single women where walking around by themselves. The apartment is on a busy street and the curtains are white. There is street light that comes into the main bedroom (not the spare bedroom), so the room doesn't get very dark. There is also a clothes washer/dryer in the unit which is always nice to have.
There are large grocery stores right across street which was very convenient. There are also 2 bus stops across the street... 2A and 8A. There is an App called "Moovit" which was very helpful. It gives GPS directions by public transportation. It takes about 1/2 hour to walk to City Hall in Copenhagen proper. We like walking, but you can take the 2A bus. We liked the location, it was close enough to the downtown area that we could walk, and far enough that we weren't surrounded by tourists in the evenings.
We needed a smart phone app to get the keys to the apartment. This was new to us. Also know that luggage needs to be carried up 2 flights of stairs.
All and all, we were very happy with the unit and would definitely stay again if we were in Copenhagen.
