Airbnb makes it a simple and very seamless process. They did a background check and asked me to upload my passport and driver’s license. It took 10 days to be approved, and no one ever came out to vet me or the experience itself. Their platform was very user friendly.  Not like Viator, which is a little clunkier.  I’ve had the chance to meet Joe Zadeh, former Head of Airbnb Experiences, and Hyun Lee, who is their Market Manager in San Francisco. Both of them are great and very receptive to feedback.
