@Tiana941 Am I understanding this correctly, you have a 'motel' and then you have a house that you rent as a bed & breakfast? You can list individual rooms on Airbnb, so you would have a listing for each room, and then if you wanted to offer the whole house you would have a listing for that as well.
You would need to make it very, very clear that it was a shared space and explain whatever access the motel guests would have to the space.
I would think your biggest challenge would be syncing up the calendars so you didn't get double booked on more than one platform.
