I was with my sister two weeks in the airbnb apartment. I must say, the people on site (with us it was a man who also gave us the keys and showed everything) was totally nice and very very helpful.
The location of the apartment PERFECT, there is absolutely nothing to complain about, because it was a safe place, close to public transport and to the also accessible by foot everything. The apartment had no mold and we got the apartment spotless.
Still, there were a few things that caused problems in the long run.
Since I work on my MacBook, I was dependent on the wifi, but the Internet did not go over several hours or is down. This was very annoying.
Many things were broken in the apartment, for example the mirror or the toilet key hung down on the right. I think for a short stay, the apartment is suitable.
