My wife and I stayed at Nanna & Bjarke's 3 nights in wonderful Copenhagen. Communication with them was excellent since the very first time, and they've been very friendly and kind hosts.
Public transport is just 150 meters far from their place, and it's very easy to walk around the city from theirs.
The room and the apartment are very 'hygge' ;), with lot of light and they're much better in real than in the pictures :)
Thank you very much!
