I have some STRs, I managed them in USD so the currency is a non factor, but I had to basically find some random address and rename the nickname. What I propose that would be easier is if no address is found, to enter “Other” perhaps and Manually enter an address that does not go on the Google maps API.
I could then enter the address, country or name and keep that a bit more organized. Even allowing me to enter the country would be nice.
