}This response contains multiple addresses nearby the location specified by the latitude and longitude. I am interested in extracting the locality from this response.
For example in case of above query, the location is Saket which is located in Delhi, India.
If I try to limit the results based on filtering on address type, it only limits the number of addresses in response and still returns multiple addresses.
How can I extract exact or approximate location?
Any help appreciated.

Geocoding is not one-to-one; a single lat/lon corresponds to multiple things. The best you can do is to rank them on importance (Google already does this) and pick the most important one. You can also sort them based on your own parameters, such as the distance to your query point. But there is no way to guarantee exactly one result.
