We visited Copenhagen with three other couples and the apartment was perfect for 8 people with two more bedrooms to spare.
The location was amazing within few min walk to most attractions, restaurants, shopping.
It is a great option for a large group/family with plenty of space not to fill crowded.
Apartment has 5 floors, with two bedrooms on the last three floors, a large kitchen area on the second floor and a foyer with bath/laundry room on the main floor. It has lots of steps and might not be suitable for a person who has trouble with climbing stairs.
The apartment was clean, had all necessary amenities and the owners were great in answering all of our questions in a very timely manner. Overall it was a great experience and I would highly recommend to anyone looking for a centrally located place when visiting Copenhagen.
