We had the best time in Copenhagen and staying at William's apartment was perfect for my family and me. The apartment is very well located - close to a beautiful park, 3 supermarkets and walking distance from all the main attractions. Our 1 year old had the best time playing with all the toys that were in the apartment. The only thing a bit tricky was doing the laundry (drying room in the basement of the building next door) and bathing our son (no bathtub). But the rest was all perfect! William and Sarah were super nice and easy to communicate with. If you are traveling with little ones - this is a great option!
