Airbnb lets us write our listing in different languages, but actually only the "Description" tab under "Listing" allows hosts to write in different languages. And this is not the only tab, where we can write text. There is also a text box called "Additional rules" under the tab "Booking" but so far I found no way to provide it in another language, the multi-language menu disappeared when I'm on that tab. And this "Additional rules" appears directly on the listing, after a guest clicks on the thumbnail and ready the whole description. So, all the rest is translated but not that part, and this definitely looks quite weird.
So Airbnb has to also provide a multi-language option for this tab, and actually for all the other tabs, even those who can be read by the guest only once the booking is accepted.
