The apartment was really lovely, stylish and well-equipped. We felt very much at home. ;-) It is close to the central station and you have plenty of options for food & drinks around the corner, which is great!
There are only two things that you should be aware of before you book the apartment:
1) It was very loud outside during the night (party goers lingering, laughing and shouting on the street till about 5 am, garbage collection starting at about 6 am and construction noise from the bar that is currently being renovated next door starting at about 8 am). After two nights, we resorted to wearing earplugs.
2) There is no door to separate the bedroom from the toilet. Depending on your relationship status and/or your cultural background, this might be a little weird. There is a second toilet on the groundfloor, but the door does not close properly (there is no handle and no lock).
Apart from these two things, we'd definitely recommend the apartment!
