We enjoyed our stay at Christopher's apartment. It's a short walk from the M3 metro stop. It's close to a grocery store and many restaurants, as well as some fun shops on Jægersborggade. The apartment was great for our one-year-old baby - the separate bedroom was helpful for nap times, and the elevator meant it was no problem to bring the stroller up to and down from the top floor. Every room is well appointed for relaxing in between sightseeing trips. Christopher is very responsive and helpful. I would definitely stay here again.
My only negative thing to note is that the bars down the street got a little loud on Friday and Saturday nights, but I don't hold that against the apartment because this is a city! Perhaps in cooler temperatures the noise wouldn't be noticeable if the windows were shut, but we visited during a heat wave and needed to keep the windows open.
