So the coordinates in the Get Directions URL are auto generated by airb&b, from the postal address?
This is the example I had:
Get directions
https://maps.google.com/maps?daddr=36.761028,22.563999
That points into the middle of the town, but the property was several miles away. The postal address provided by the host (well, the one I could see) listed just the name of the town (the district).
Whereas your average customer will load 36.761028,22.563999 into their satnav and.... 🙂
More importantly, the customer is likely to use the "Get directions" link to verify that they got the right place, so if the description is slightly vague ("5 minutes to the beach" instead of the more correct "5 minutes drive to the beach", in my case) it would look good. Please bear in mind that airb&b listings show only vague locations and this remains so (in most cases) even after the booking has been confirmed.
