Yes, I am serious! I think that Airbnb is also serious....
Please Go to Airbnb Menu -> Listings > Booking Settings > Things that the guest should know about your accommodation before booking.
As for listing "everything you don´t have" It is up to your crazy imagination 🙂 I have never said that.
Anyway I will explain to you what a host should list if the listing DO NOT have...
For example:
1- If an apartment is on the 5th floor and the building has no elevator, the guest should know in advance.
2- If the sofa of your living room has only 3 legs instead of 4, the guest should know in advance, unless you want to receive 3 or less than 3 stars and then come here to talk about "... absurd thing you lost a star for"
3- If you have a holiday house to let, and the guest has to use a car everytime he/she goes out, and the guest CAN NOT open the garage gate using a remote control, it is a good idea to tell them in advance. (just my opinion)
4- If your house has a swimming pool that are always empty, you have to let the guest know in advance, unless you want to receive 1* overall.
I think the examples aforementioned are enough to understand "why on earth" someone should let the guests know what is NOT available in a listing.
Just my opinion!
