Apparently, Airbnb attempts to create a postal address from any Google maps link. In our case, we don't have a postal address, so Airbnb send the guests to the nearest postal address, which is about 3km away.
I've simply written in the instructions that are sent to the guest automatically, that the Airbnb location is wrong, and they should use the link I provided instead.
In addition, we send the correct google maps link by WhatsApp a few hours prior to their arrival.
