If you want to list multiple rooms in your house, you can create a separate listing for each space you have available. Each room will have it’s own calendar and listing page that should accurately reflect the number of beds and amenities, as well as what space will be shared with others.
To create a new listing, log in to airbnb.com and go to List your space.
You can also create a listing for your whole house and separate listings for individual rooms in the house, but be sure to sync your calendars. If you rent your entire house, block those dates on all the individual rooms so you won't double-book.
You can offer guests a discounted rate for booking multiple rooms by sending a Special Offer and blocking the calendar of the other listings to avoid double-booking.
ME: I would suggest you give each room a unique name so you wouldn't get confused...just saying.
