My stay at the H.C. Andersen house was wonderful. It's located in a beautiful spot, easily walkable with tons of local restaurants and attractions nearby.
Checkin is simple, and the place felt secure. The bathroom was clean, as was the rest of the apartment. The space was warm and welcoming, with plenty of character but not over-done or obnoxious.
I really enjoyed my stay and wouldn't hesitate to stay again, should I make it to Copenhagen in the future.
