We really enjoyed our stay in Copenhagen! The location is perfect, close to the bus and metro. It's easy to get there from the airport, and really close to the city center. It's close to a big street where you can rent bikes a grab something to eat.
The apparment is what you'd expect from the photos. The shower has good water pressure, the only problem is you're basically standing in the sink and there's not much space to put your clothes. The beds are good. The kitchen contains all necessities to make a simple breakfast, but don't expect to be able to cook a full meal.
Overall, a very nice place with a great quality/price ratio to spend for a citytrip. Would definitey recommend it.
