This was a great little apartment. We were a group of 4 girls and the flat was perfect was that. The location is perfect, close to many attractions and places to eat out. The flat itself has a great Scandi-style décor, was very clean and nicely equipped with everything you could wish for. The flat is on the dark side (in terms of lighting) but that wasn't a particular problem for us, although we noticed some of the light bulbs were not working when we stayed.
The only thing to note is that the flat is next to a bar / nightclub, so it was pretty noisy on the Friday night, a little less so on Saturday, but I think you can probably expect some noise over the weekend. Again this was not a problem for us - it did not prevent us from getting a good night's sleep, but if you are a sensitive sleeper perhaps just bear this in mind. Also there is no lift in the building. The flat is much better reached by metro - don't bother getting a taxi from the airport (which is quite expensive)!
All in all, a great stay.
