Hi @Chris861
It absolutely drives you potty, had the same problem a while ago.
Put in any address that it will accept and you can alter the address and location pin after publishing the listing. if it still won't accept the new address after publishing, you have to contact airbnb with the address and longitude and latitude coordinates as in the message below.
How are you doing today? My name is Alex and I am Case Manager from Airbnb.
I can help process a one-time, permanent change to your address.
To do this, please visit itouchmap.com/latlong.html to use their tool for finding the latitude and longitude of your listing and provide us the following information:
1. Latitude and longitude GPS coordinates (please copy the decimal form, and not the degrees/minutes/seconds)
2. Apartment or house number
3. Street name
4. City
5. State, province or region
6. Postal code
7. Country
If you have more than one listing that needs to be updated, please be sure to specify the information for each listing separately by including the name of the listing along with the listing's web address on Airbnb.
