My partner and I had a great stay at Karen's place. The flat is well located in Valby, with easy access to the city and also the main train line to Roskilde. There are supermarkets close by as well as restaurants. The flat is very nice and cozy. The bathroom is very small, but works well. The balcony was really nice, and would have been lovely to sit on during summer (we visited in February). Note that the building is old, so you can hear the neighbors through the roof and floor, but that's just how old buildings are in Copenhagen, and it didn't bother us much. Karen was a very good host. She was very helpful, proactive and responsive. I highly recommend the place.
