Hey Eddie,
I am currently an undergrad at UC and will be attending medical school there next year. Anyway, the majority of UC students live in Clifton. Clifton has good sides and bad sides; Clifton Gaslight is good (and expensive), Corryville is not so good, Clifton Heights is decent.
There are also a couple of neighborhoods near campus that some students may stay in; Avondale, which is very close to the hospitals, is not a very good neighborhood; Hyde Park is lovely but, surprise surprise, also expensive.
Those are just a few ideas for you. You're welcome to email me if you have any more questions.
I guess I'll see you next year.
