apartment listing & filterng plugin Wordpress

We are looking for an vacation apartment listing plugin similar to the one in this theme: [login to view URL] We want to use it as a plugin in another theme which is responsive to smart phones and tablets so an advantage if the plugin is too. I know there are many free and cheap ones on the net but no one have appealed to us yet. User friendliness and a professional look is important. This is the theme we have in mind to use for the project: [login to view URL] This is only a request for the listing plugin and not for the whole theme. If you already have what we are looking for in stock, please share with us where to look and purchase. If you can develop a listing tool like that, please get in touch.
