Why should there be only one reason? It has been obvious for years that design is a huge factor in Airbnb's success, and that it's a lot more than "bright pretty pictures". That shit is hard and they nailed it. I'm sure they did some other things too.
Founders at Work is a good example of painting a better picture -> http://www.amazon.com/Founders-Work-Stories-Startups-Early/d...
I think everyone knows better pictures are better, but I don't think anyone realized how much of a large difference it could make--especially in their area.
—Oh here is a copy I found real quick. As far as I know, they hired a few photographers, saw a statistical difference, and then decided to hire 20 http://i.imgur.com/VpYTF9L.png
Probably because it's difficult/impossible to identify the real causes of any company's success and we want to attribute it to something we can digest. This podcast episode on Survivorship bias is very relevant: http://youarenotsosmart.com/2013/05/23/survivorship-bias/

Bright pretty pictures give a pretty damn obvious advantage.
Neither design played a huge role, nor "meeting their customers face to face". The world is filled with failed startups with great design.
The simple explanation is: they simply offered a product people needed for it's value + some luck.
But I guess the product having a use value (as opposed to nice design or soapy stories about "connecting" with their customers) does not cut it as an offering anymore.
