I'll poke my head in here just to say that as someone who grew up and lived for 18 years in Rochester (never as a student), it would be very, very difficult to live and enjoy oneself in this city without a car. Rochester has its cultural delights, but they are extremely spread out - this is a city that has suffered big time from major sprawl. Also, the weather is more bleak than straight up bad. Yes, it gets cold and yes, it is snowy, but more than that it's just gray very, very often. If you suffer from any kind of weather related depression, take this into account.
Rochester is an excellent city in many ways - tons of gorgeous parks, a vibrant (if somewhat hidden) arts scene, great (if simple) food and an hour and a half away from one of the nation's best kept secrets, the Finger Lakes region. However, bear in mind the two points I made above when considering quality of life here.
And I'll also mention that RIT is far more out of the way from pretty much anything than U of R, so I'd underline the car point if you're planning on attending the former.
