Superb location - really, can't be beat. You're right in the center of old Copenhagen, an easy walk everywhere. Spacious rooms, nicely furnished. We didn't meet the owner until departure, but that's fine - checking in and storing luggage was easy and fast with the help of the people in the owner's restaurant next door.
Our only problem was noise - the ceilings are thin, and each upstairs footstep was audible; seems every moment we spent in the apartment the guy upstairs was doing heavy laps from one end to the other. Obviously this is not the owner's fault, but it was our experience anyway.
