i am a 4th yr med student at Newark. i'm also going into anesthesiology, but at Northwestern.
first off, congrats on the match. as for housing...i wouldn't live in newark...most students and residents don't. some cool/trendy towns popular with young professionals is montclair, wayne, bloomfield, there abouts. there are bargains to be had if you have time to look. there are a few luxury apt buildings...even still, the rent there are still cheaper than NYC. as for parking...the security on campus isn't too shabby. i would park in the covered lots....and obviously lock your car up as you would anywhere. i wouldn't walk outside late at night without a security escort or with friends.
have a good time a newark...its trauma heavy...plenty of stabbings, shootings, MVAs to keep you busy 😉
