When you checked into your Airbnb, you noticed the sink was already acting up but didn't think it would turn into a big deal. Fast forward to checkout, and suddenly the host is blaming you for a plumbing issue and sending you a bill for repairs. How can they charge you for something that was already wrong? And do you actually have to pay? The good news is, Airbnb doesn’t just take the host’s word for it. You have a chance to fight this, and how you respond right now can make a big difference.
