We had a wonderful time in Nanna's beautiful apartment. It was located perfectly for us 5minutes walk from Frederiksberg. The area is very nice, with lots of coffee shops, restaurants and bars scattered around. It is a very easy 2 stop metro ride from the centre of Copenhagen and 10 stops from the airport so very accessible.
The apartment is simple but stylist and very clean. My only negative was that there was no iron.
Nanna greeted us on arrival, then left us to it but was on hand if we needed anything.
Overall a great place to stay :)
