Never heard of an organisation using Airbnb to find accommodation for displaced families by contacting hosts directly. @Kristin931
Tell them if they are working with displaced families they should use this https://www.airbnb.co.uk/openhomes and that under Airbnb's T&Cs you are not allowed to accept third party bookings or provide an address before booking.
As a new host I would suggest you limit your stays to one or two weeks until you become more familiar with managing your listing.
Airbnb Help is a useful resource for the basics around running your listing.
