@Lisa5185 - you'll probably have to contact Airbnb to get your personal account reinstated.
Yes, I misunderstood what you were talking about regarding handling your boss's account. I thought it was for travel.
If you are going to manage his Airbnb listing, he needs to create a profile and a listing in his name, get verified, and enter in his banking account information. Once that's complete, you can be added as the co-host and be made the primary host. As the primary host, you will be the person that is called in the middle of the night when there is a problem with the property.
