We stayed at the apartment for three nights and loved it! It is very clean, beautifully furnished, with lots of lovely details and all the necessities one might need. Also, the bed was incredibly comfortable, perfect after long days of walking and sightseeing!
Mette and Anders live in a very cool neighbourhood: although their apartment is in a very quiet street, which allows for a good nights' sleep, you can find plenty of hip bars, lovely cafés and excellent restaurants just around the corner. The public transportation is great as the bus stop is basically in front of the apartment, but you'll probably spend most of your time in Copenhagen just walking or riding around by bike.
We would definitely recommend to stay at this place, especially if you're looking for something slightly off the beaten track and in a charming, lively area where you can mingle with the locals!
