I quite enjoyed my stay. The apartment looked like the photos, it was clean and quiet. There were a lot of nice restaurants and cafe's and you could walk most sights, so it wasn't even necessary to take the bus. I already had shampoo in the bathroom, which was really nice.
One thing, I didn't like: The WiFi was a bit slow, so it is not recommend, if you want to work (or you work from a nice nearby cafe). But all in one: Worth the stay and thanks for all of the advices and tip's!
