Katja was there waiting when we arrived and that made us feel very welcomed. The street they are on and the neighbourhood is very nice. Public transportation is nearby but we were able to walk to all the sights. Their place is spacious and comfortable and my family of 5 adults and a toddler really enjoyed our stay. I would recommend Mark and Katja's place when visiting Copenhagen. For the elderly and disabled, the flights of stairs to their flat may be a challenge.
