<p>1) Columbia is not in Harlem it is in morningside heights. BIG difference. Morningside Heights is the second safest neighborhood in NYC.
2) If your interested in museums, the choice is a no-brainer. MET, MOMA Guggenheim etc are all free access to Columbia students. (You just need your Columbia id to get in). The exposure to museums in NYC is simply unparalleled.
3) Columbia has a great neuroscience department (cant speak for Harvard here though).
4) Columbia has a wonderful language program and its own language resource support with extensive support for languages (Ancient Egyptian for example). </p>
<p>I would research Columbia more if I were you because no offense, but you sound pretty uninformed about the opportunities it has to offer.
Lastly, congratulations.!</p>
