My boyfriend and I had a great stay in Karsten's apartment, he was very helpful all the way through the booking and meeting us at the apartment when we arrived. The room was large and very clean, the shower was one of the best we'd had after 3 months of travelling! There is a tram which runs around every 20 minutes which is quite loud, but not loud enough to wake us once we were asleep. However, this means there is transport straight into town right outside the door!
