We had a lovely stay at Cecilie’s! She was very accomodating and trusting. The apartment is beautiful, on the fourth floor (no elevator) in a very old house close to the city center. I bought a metro card but it was unnecessary as we were so close to the center of the city. We were able to walk everywhere we liked in the three days we stayed in Copenhagen. I would love to stay at Cecilie’s again some time as I genuinely loved it there.
One thing worth mentioning is that it is a residential building so there is a lot of life there. You need to be quiet in the late evening and night and might wake up to kids crying or playing in the courtyard. I found it charming but others might disagree.
