How can I got city name using google map API

I already got the latitude and longitude of my location using this Unity - Scripting API: LocationService.Start tutorial, however; I need to convert the latitude and longitude into the city name. I don’t need to pinpoint my location on a map, I just need to get the city name. Any suggetions on how I can do it? Also if it will help, I’m using C# in my game. I’ve pretty much read all about Google Maps API but I still am far from understanding it. Any recommendations would be much appreciated.

If you retrieve this JSON data (fill in your longitude and latitude): https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true you can find the city name from that.
