I like it. My 2 cents regarding the UI:

1. Labels under the filter area look like buttons, I always want to click one of them :-)

2. The "sticky" top with map and filters and the scrolling list at the bottom I think not the best UX decision. I have a relatively small screen (1028x1024) and I almost don't see the list. Maybe the solution would be to be able to collapse the filters and map (and bring the map by clicking on the map icon from the listing).
