Great place to stay! Easy to walk all around Copenhagen from here, very central. Apt was very clean and comfortable. Aperon has a wonderful group of staff - coming from the States I had many questions and they were very prompt with answers and so kind. We were a group of 3 women and all said they'd love to stay here again. Big plus is they have a place to leave luggage after checkout.
Small drawback is no elevator and I forgot when requesting a room on the 2nd floor, that it's really the 3rd floor in Denmark.
