According to Airbnb co-hosts help listing owners take care of their home and guests.
A co-host is someone the listing owner already knows. They are usually a family member, neighbor, trusted friend, or someone the host has hired to help with the listing.
Hosts and co-hosts agree on who's responsible for what, how much of the reservation income will go to the co-host, and how the co-host will be reimbursed for expenses.
