I had a guest whose behaviors included: illegal downloading that shut my internet off (and i work from home so that was a huge 1/2 of work spent resolving the issue); getting drunk and losing the key; keeping dirty dishes under his bed; being drunk and break my (vintage, antique) glassware in the kitchen; and more.
I left a bad review, which he deserved. Apparently, he contested it and Airbnb took it down! I forgot to mention that when I called him out of his inappropriate behavior he said, "watch it, I have a key to your house." ... And now no one will know that this is the creep they are letting in... What in the world is wrong with Airbnb. I am very against this system now and am going to shut down my house, as their vetting process is clearly worthless or worse.
