Specifying zoom level at startup seem to fix the problem:

,----

|   "Run Google Maps on LOCATION.

|                               (or (thing-at-point 'sentence) ""))))))
|   (let ((location (if no-geocoding

|                     (google-maps-geocode-location location))))
|     (google-maps-static-show :zoom google-maps-static-default-zoom
|                              :markers `(((,location))))))
`----

I use 10 as default value for `google-maps-static-default-zoom'.
