I had a great stay at Carsten's apartment. I booked the place day-of, giving Carsten almost no time to prepare for my arrival, but he was communicative, check-in was easy, and the place was very clean. He was kind enough to give me some great suggestions as to things to do in the neighborhood and around Copenhagen. The location was excellent, in a lovely neighborhood full of great food and bars that's walkable/bikable to pretty much everywhere you'd like to go (and with a bus stop right outside of the door).
