I stayed here for two weeks and had a fantastic stay; I can't recommend it more.
The flat is lovely, bright, clean, and has everything you need; the guest bedroom is large and comfortable. The location is great, with public transport, grocery shops, and a park very close by. The area is safe and it's a good base for seeing the city.
Julie is the perfect host - friendly, flexible, and helpful. She is also an easy person to share a flat with, and respectful of the guest's privacy. She always responded really quickly to messages, and of course, had great suggestions for things to do in Copenhagen.
I definitely recommend it to others and hope to stay here again if/when I come back!
