Short story: the apartment is FILTHY and the communication with the host is EXTREMELY BAD!
Upon arrival we found a lot of dirty surfaces, some mold, and some hair in the shower. The curtain was also broken and most products in the welcome bag were expired. We were willing to let this all slide, until we came back to the apartment our first evening to find a pool of water in our kitchen. The water had been dripping through a lamp in the ceiling. This is not only very filthy, but also a fire hazard.
I have tried contacting the host several times about this issue. I used all the numbers to my disposal, but none of them answered. Even the so-called 24 hour emergency assistance number immediately cuts off. This is not okay. The communication has been lacking since the beginning. The host never answered on Airbnb, and after a few messages on Whatsapp, they also stopped answering there.
Also, we arrived back at the apartment several times to find a hazy mist in the apartment, even though the windows were closed.
