Kristoff is a great guy and that makes the difference.
He left a full can of coffee, so my wife blagged him for tea bags.
He left beer in the fridge, so I drank it.
He gave good recommendations for bars and restuarants, so we followed them up and had good times.
The apartment is very clean, warm, well located (genuinely ten minutes hungover walk from the centre) and very easy to navigate from and to.
