It was our first time in Copenhagen and we had a wonderful stay at Marie's apartment. The location is excellent, very close to a road with an amazing bakery and coffee shops, nice little shops and a Michelin restaurant.
We used a christiania bike to move around and everything was at a close distance (within 30min max cycling) from the apartment.
We were travelling with our 16 month boy, there were toys in the apartment that he could play with, a highchair, a small playground on the back patio and a park with a big playground just around the corner.

We highly recommend Marie's apartment to couples or young couples with little kids!
