The location of the appartment is really perfect. Right in the city center.
However, the flat is located above a club and a quite busy street, which means it is a bit noisy mainly during the weekends. You also hear your neighbours a lot.
We had a pleasant stay. The room was clean but stinky (probably from the sewage). Otherwise, we only had one problem by our arrival. Other guests put their stuff in our room as they thought it was theirs. It was not nice coming and seeing other people have been in your room. However, the host resolved the problem quickly and we could checkin in our room without further problems.
