This was a great stay for a family of four with two children! Best location, central to pretty much everything (metro, shipping, historic attractions, within a very enjoyable stroll). The Torverhallerne Market, within 2 minutes walk, is a must see and experience.
The apartment is nice and clean, with all the amenities one would expect in an apartment and hotel at the same time. We did not use the kitchen, but was well equipped with everything one needs. The luggage storage is very accessible in the basement and a nice to have if apartment is not available for early check-in.
The host was very accomodating to our requests (early checkin, extend stay due to flight cancellations, order cab very early in the morning for the airport). All our questions were answered within minutes via chat or phone. I would definitely come back and I would recommend it for anyone visiting Copenhagen!
