If you are traveling with large luggage and/or with older individuals, this might not be the best bet because it's located on the 5th floor with no elevator (4th floor in Demark is equivalent to US 5th floor, as the first floor is considered "ground floor" there and the second floor is "first floor"). Other than that, staying with Karen was super convenient -- her place is wonderfully furnished with plants and her artwork everywhere, plus she has an adorable little pup named Nova! She goes over house/kitchen/bathroom rules and how everything works when you arrive.
I would highly recommend this place to travelers who need a few nights in a conveniently-located area. Vesterbro (the surrounding neighborhood) is super cute and filled with great eats!
