A first class experience.
Mads himself is a lovely host who left detailed and helpful instructions about locations to visit, places to eat etc.
His apartment is very nice - and is actually two apartments in terms of size. It's very neat and modern also. I found myself very comfortable here.
The location is lovely also: quiet, yet central.
All told, I would have zero hesitation in recommending both Mads and this apartment. A very positive place to spend my time in Copenhagen.
