The stay at David's place was great. No negative sides at all. The apartment was exactly as described and had everything you would need during a trip. It was also very stylish and comfortable.
David even gave us an extra set of keys and brought us an iron that we needed. Check-in/out was very easy.
The metro station was very close and the location was very nice, within walking distance from the center.
I would definitely stay again at David's place if I ever visit Copenhagen again.
