Carsten is a great host.
He was helpful and caring, explaining us local things, giving recommendations on what to try, where to go, etc. and making sure we were comfortable and have anything we needed for our stay.
The flat is well positioned with a tube station within 5 min walk. There is also a sort walk from the flat to the City Centre (15 min) and to Christianshavn (20 min)
The room is big, nice and quiet. There is a wardrobe to leave your stuff and the bed was super comfortable.
