We had a great stay at Kathrine's lovely flat. The flat is in Vesterbro, a really interesting district of Copenhagen, and is within easing walking distance of the main train station and all the sights of central Copenhagen. To the west, a thirty minute walk will take you to Fredericksburg Gardens and the Zoo. In Vesterbro itself, there are plenty of nice cafes, shops and bars, and there is also a Lidl five minutes from the flat which is really useful for groceries.
Kathrine sent clear and detailed information in advance of our arrival, including directions to the flat. Check-in was really simple - keys are collected from a key-lock box at a nearby café - and when we arrived we found a welcome note, guidebooks, and some delicious treats waiting for us. Kathrine invited us to use what we needed in the kitchen, pantry and fridge, and left plenty of towels for us to use. The whole flat was warm, comfortable, and spotlessly clean.
Overall, a wonderful place to stay and I highly recommend it.
