The flat hasn't been cleaned at all when we checked in. The floors across the whole apartment were full of hair and surfaces (floors, tables) were sticky. The dishes were dirty, so were the cupboards and the shower. You could clearly see that this apartment hasn't been properly cleaned for a long time. After reporting to the host, they offered additional cleaning (which would've meant I'd had to leave the flat for half a day, which wasn't possible because I had to work from the flat). Since the initial experience was that disappointing, I just wanted to leave. The host didn't agree to an early leave, so I had to involve the Airbnb support, who luckily was able to handle everything and got me a refund.
