We never met Claus, but his friend was able to provide us with the keys with no problem. The apartment was in a great location. For public transit, the nearby bus stop had buses stopping by near-continuously; for bikes, there were options at all price ranges (we ended up renting from Loke, since they rent on a 24-hr basis and we were picking up bikes late in the day). Great A/V setup. Would definitely stay here again next time we're in Copenhagen.
