One offer, two cities

[PhantomTollbooth]

:Situation:
I received an offer for a summer internship at a company for two of their offices. Specifically Charlotte NC, and Washington DC. The only additional information about the company that seems relevant is that DC is the home office and Charlotte is a bit smaller.

:Question:
Where should I work? Answer this question based on any criteria you like, personal experience, impersonal experience, rumors, stats... etc...

While I'd love to hear quality of life comparisons between the two cities, I am more interested in hearing contrasts between the job market in the two cities. I have many people with differing opinions on the former, but you, the public on this forum, are in a unique position to answer the latter.

As always, thank you everyone for your time, there is no better resource out there that I've found.
