Kathrin's place was as described. The location was perfect for hitting up the Meat Packing District where there is great food, beer and night life. We walked everywhere. Very cosy, can tell it is a home and not just a rental.
The beds do not have bed-frames, rather are low to the ground. No issue, just weren't expecting. Small bathroom, but not an issue. Towels were very tiny, more like hand towels than body towels.
Would stay again if in Copenhagen.
