Just Accepted for an MA Program...Quality of Life/Transportation Questions

I was just accepted for a MA program in Psychology. I am wondering if any current or former students could
enlighten me with respect to the cultural dynamics of NYU, the lifestyle advantages/disadvantages of Manhattan, the personality of the university, the quality of the Psychology program(both undergrad and graduate, but if you can only speak to the undergrad program that would still help me out) and the transportation logistics for a campus that seems pretty spread out.

I am also wondering whether in a MA Psychology program you could cross-register with graduate level electives in say Creative Writing/ Philosophy? (I could probably find this out elsewhere but for convenience purposes I am asking current or former students)
