Then I guess career-wise NY is a no-brainer, LA seems more like a fun place to go.
You don't have to live in Manhattan, try getting a place in Queens or Brooklyn, preferably near a metro stop. You can take the metro and be there in a couple of minutes.
Yeah and I also have the possibility to extend my stay with another semester for an internship in NY.
living outside Manhattan would be the solution as you said and if I am not wrong you can get a monthly pass for public transportation for 100$ or something.
Well it is clear to me now that NY is the wiser choice.
