How to get 3rd level deep data into jqGrid

How to get 3rd level deep data into jqGrid

I am getting the following JSON response from a web site :

http://pastebin.com/5cJt7VV8 (example with 10 results)

I want to get these 10 results in a jqGrid, but only 4 columns -3 level deep- hotelId, name, address1, city.
Is it possible?
Thank you.

PS: If it is possible, give an example, because I am new to jqGrid.
