Carolina's apartment is in an interesting, picturesque part of town and very near a metro. She wasn't there during my stay, but thoughtfully arranged for me to access the apartment and a bit earlier too. The room is big and comfortable, but unfortunately, there was no hot water in the shower and the WiFi didn't work, which I hope have since been fixed, but may be worth checking. Otherwise, it's a nice place to stay and good base for exploring Copenhagen.
