Location auto complete lookup

I have a client that wanted to add the ability for the client to have an autocomplete of location names.
I started thinking of how to implement it and from where to get the information for the location names.
Then i came across of the following service:

Google Places Auto complete: https://developers.google.com/places/documentation/autocomplete

A blog that explians in details of how to use it can be found at:
