The flat is much as described, and recently furnished, so everything is pretty much tip-top. Flat is warm, and besides some noise when people use the staircase, incredibly quiet and calm when you consider how central it is.
Location is pretty ideal for people who wish to explore Copenhagen, with most things literally just outside the door. Communication, check-in and similar worked very well.
Some slight hiccups, though. Warm water ran out on us at one point, which seems odd. The wifi doesn't work all that reliably, but could always be fixed. No showergel or similar, which seems a strange thing not to have with this kind of arrangement and this pricepoint (it might have said in the description, didn't even think to check).
Overall, a nice little place, great for exploring Copenhagen from, particularly for a small family or similar – the place might sleep four, but you would need some creativity to comfortably live and cook with four adults in here.
