Great location if your stay is related to some academic activities in the University of Copenhagen campus. Biking or public transport is advised for visiting the city center. Otherwise, it's going to be about 30 minutes walk. Smooth check-in and check-out. Well-equipped kitchen. If you're worried about the small bathroom after reading some other reviews, stay reassured - it's perfectly OK unless you have some mobility issues.
If you don't like cold apartments, be prepared to do some bargaining (or avoid booking in fall/winter season). When I first came to Anna's place, the default option was a huge balcony window in the kitchen to be open 24/7 at the end of October when there was ca. 10 degrees centigrade (=50 Fahrenheit) outside. I also had this impression that Anna was rather indifferent towards me which I found a bit uncomfortable but maybe it's just cultural differences.
All in all, totally decent value for money, safe, and transparent.
