it's not working for me either and it's really ticking me off
the blog post is : http://aroundlawithtk.com/buy-black/one-bedroom-airbnb-apartment-for-rent-inglewood-near-sofi-stadium
and the airbnb listing i'm trying to embed is : https://www.airbnb.com/rooms/53162599
i followed all of the steps, exactly as instructed, and it's not embedding.. grrrrrr! instead, it's a blob of code in the middle of the blog post
