 Let me start by sharing an anecdote, something that happened to me recently. I was visiting Madrid for a conference, so I figured I would stay for the weekend with the family. One night, after putting the baby to sleep at our Airbnb apartment, I went outside to wait for a delivery. That's when I noticed a pink round sticker on the building's intercom. It read, these used to be my home. And then, hashtag, curse word that I can't say on the radio, Airbnb.
