Lise's apartment is a wonderful space in a great neighbourhood, very calm and relaxing and a great base to explore the city via bike (rented locally).
Lise was really helpful with sharing local tips for great coffee, art museums and live music and was very quick in responding to our questions.
It's been mentioned elsewhere but you have to climb to reach the bed as it's a mezzanine, no issue for us at all, but if you're less mobile it could be a slight issue.
Highly recommend Lise's apartment, we had a great time and loved Copenhagen :)
