He rented again and the girl asked if she could rent for a few more months. So they signed a standard city lease outside Airbnb and she hasn't left or paid. He's had to file eviction. That obviously isn't AirBNB's fault, but it's now 2 for 2 bad experiences that started with AirBNB.
I wonder how many people install cameras in just the entrances/open areas more as a general liability thing. It probably goes against Airbnb policies, might be unethical or illegal in some jurisdictions, but considering the horror stories on both sides, I can understand why it happens.
