The flat had a really bad smell coming from the drains that the hosts gave a lot of explanations for but could not fix.
The downstairs neighbors are super loud, smoked and played the radio all day right outside the window. I was told to complain to the police if I had a problem with it.
In the end, I had to escalate it to Airbnb and they got me out of the flat. All in all, a rather unpleasant experience
