Fetching geo-coordinates is in my eyes no domain logic - this could also 
be some foreign service. And it was just a suggestion. As I don't know 
the main purpose and implementation of this I can only give suggestions.

In that case I would use a private property and store the transient 
"location" coordinates there like suggested before.
