Carsten place looked way worse in person than it did on the pictures. The beds were uncomfortable, the kitchen was a mess when we arrived, and the bathroom/shower wasn't clean. The apartment had a specific odor that was quite unpleasant and didn't go away, no matter how long we kept the windows open. I feel that a more honest description of the place is appropriate.
During my stay, I lost the key to the apartment. Carsten gave me another one but requested that I pay 200 DKK for a replacement key (seemed a little stepp for a key). I paid him and asked for an invoice or a receipt (or any proof of payment, as of that matter), however Carsten refused to even try and get me one. He was very uncooperative and this experience spoiled my entire trip.
