My last Airbnb experience was six months ago. A room rented in an old Silverlake home. It was a superhost with dozens of rave reviews. The woman who owned the house was in her 80's. A few weeks in to my one month stay, she knocked on my door at 10PM and asked me to get ice for her at Whole Foods. When I declined she began screamed profanities, then proceeded to blast calypso jazz for a few hours, among other things.
She had some sort of dementia which is sad, but I could not comprehend how she had been a superhost with Airbnb for years. That is, until I left a review of my experience and Airbnb promptly deleted it. I'll stick to hotels from now on. As far as LA apartment hunting goes I still think I made it out unscathed.
Oh, also I started shorting $ABNB shortly after this experience and it's almost made the whole thing worth it.
Edit: It feels really good to finally tell someone about this. It was so bizarre I'm too embarrassed to tell friends or family.
