We had very nice stay in Kathrin's flat. Flexible arrival worked perfectly despite it was Kathrin's boyfriend welcomming us.
Location of the flat is excellent. 200m from railwaystation and 500m from some of CPH best restaurants.
Beds were bit wornout and small for 2 persons but for short stay they are OK.
I have to mention that my wife really moved the design of the flat :)
I can warmly recommend Kathrin as host and her flat as Location where to stay in CPH.
