Ulrik is very reactive and has a smart technique to leave the keys so you can arrive at any time even at night there is no problem (and public transport runs 24hrs in Copenhagen).
His apartment looks just like the pictures, very "Danish design", we loved it! The apartment was clean, and the bed comfortable. It's located next to a park so you can hear the birds when you wake up :) be aware that there is a lot of light in the room in the morning.
We loved the neighborhood, day and night! It's not actually the very center of the city but we did almost everything by walking (I guess it's different when it's raining...)
Just 2 problems: the light didn't work in the room when we were there but I'm sure Ulrik will have it fixed soon, and no shampoo in the bathroom.
It's very expansive for the service though but this is Copenhagen prices...
