Hi there!
Great question! When listing a property on Airbnb, a bedroom is typically defined as a separate room with four walls, a door that can be closed (ideally lockable), and a permanent sleeping arrangement (like a bed). That said, a fold-out couch can sometimes be considered in the count, especially if it's in a room that meets the privacy criteria (like a room with a door that closes).
If you're listing the whole house and one of the rooms has a fold-out couch but has its own door and privacy, you could potentially list it as a bedroom. However, it’s important to be transparent in your description. Guests appreciate clarity, so make sure to note that one of the bedrooms has a fold-out couch instead of a traditional bed.
In the title or description, you could say something like "2-bedroom home, one with a fold-out couch," so guests know exactly what to expect.
Hope that helps, and good luck with your listing!
