We loved Charlottes appartement. We almost felt like home. For me personally, it represented the scandinavian way of living. The flat ist located in Amagebro, which is in a lovely, quiet neighbourhood, a few busstops away from the center. We once had a walk home and need aprox. 40min from the center, which is totally okay, if you like walking like we do.
I would recommend you renting a bike to explore the city: We rented two bikes in a shop called "Kalles Cykler" 5min away from the flat. We payed 100€ for 3 days and 2 bikes, which is fine.
The communication with Charlotte was quick and easy. I would totally recommend Charlottes appartement to everybody who visits Kopenhagen and doesn't mind staying a little bit outside the center.
