I suggest Airbnb sends hosts promotional merchandise that's useful both for hosts and guests. For example: 1. Airbnb keychains with the logo to hold the rental's keys.
2. Airbnb backpacks or beach bags for the guests to take to the beach.
3. Airbnb sticker or magnets.
4. Airbnb T-shirts or hats.
5. Airbnb pens, notepads or sticky notes.
6. Airbnb personalized business card for the host, with a link to the listings.
7. Other
I have been a loyal host with Airbnb for years. I've never used another platform. However, I've heard about other platforms that give this type of merchandise for free to their hosts.
I strongly suggest Airbnb does the same.
