Bubble uses Google Maps' autocomplete API to search for geographic locations. The API saves a place's address based on its displayed name rather than the precise pin coordinates — and for some non-US locations, this means a neighbourhood or district name is returned instead of the city.
What you might notice
Searching for a location returns an address that's less precise than expected — for example, a neighbourhood name instead of the city
This happens more frequently for locations outside the United States
Workaround
Add a hidden Map element to your page and set its value to the SearchBox input. The Map element uses the full coordinate data from Google Maps to place a pin, and its "center" property provides more accurate location data than the autocomplete address alone. You can read more in the documentation.
This is a limitation of how Google's autocomplete API returns address data for some locations.
