As a long-time user of Airbnb, this is the best experience I've ever had. I can't recommend Katrine's home enough. As another reviewer said, don't hesitate to book, just do it!
Her home is warm, comfortable, and extremely stylish without being intimidating. With gorgeous furniture, a comfortable bed, and a kitchen more well-equipped than my own (including beautifully sharp knives, so rare when renting), we looked forward to coming home everyday. There was also plenty of natural light despite visiting in late November, which was a real plus.
Fellow Americans, the bathroom is small, but showering works out well, so fret not!
Additionally, Katrine was easy to communicate with, kindly answering my many (tedious) questions, as well as providing lots of information about Copenhagen.
