Christoffer was very friendly. He met us at the house and showed us around. His place is beautiful. He gave us the towels and the key and explained about the garbage etc. and gave us a map and even told us the weather report for the next few days.
The apartment is quite well located. We took the subway most days (a few blocks walk). It's quite large and there was lots and lots of room. The beds were very comfortable. The stairs up to the apartment turned out to be no problem at all (we did a fair amount of walking in our touring of Copenhagen).
