From arrival to departure our contact person Cheryl made sure we felt welcome and had everything we needed.

The apartment itself is roomy and warm, the balcony is absolutely great. Cooking on the gas oven was a joy. The bathroom is small but completely sufficient.
As stated in the description, two of the bedrooms are children's rooms, so as an adult one shouldn't expect the comfort of a full bedroom. You're still perfectly able to get a good nights sleep though.

The apartment really is located in the heart of Copenhagen, sightseeing starts right when you step out of the door.
We rented some bikes and it felt like we needed just 5 minutes to be basically anywhere.

The food situation is even better. Stocking up in the supermarket and cooking for yourself is stupidly easy. Going out is even easier. You are a stone-throw away from excellent tapas or sushi or some awesome take-away vendors at torvehalleren.
I think you could just spend your entire holiday in a kilometer radius around the apartment and still have a grand time.
