We had a nice stay at Christine's place, the host was flexible regarding our arrival time and welcoming. The room is as described, small but nice and very light, we really liked it. There is not much place for clothes though, so good if you have small bags. The bed, sheets, duvets and pillows are very comfy and of good quality. The bathroom was nice and clean.
In case you didn't notice it in the ad, note that you only have access to the room and bathroom. It wasn't a surprise for us as we had asked when we booked, but of course not being able to use the kitchen or even just boil water for breakfast makes your stay quite more expensive given the prices in Copenhagen.
A good and peaceful place for a week-end if you like to eat out and want to feel independent!
