I am not in the SJF class of 2012, but I am in the VCU class of 2012... I grew up in Rochester (Fairport actually!) and I know a few kids in the class of 2011... anyway, best website I ever found for apartments in Rochester-
www.rentrochester.com
That's how I found all my places... I would look in the southwedge or monroe avenue area, its a younger crowd, nicely priced apartments... Near the school, theres some complexes, but not much in the way of apartments with character...
Also, please beware of renting from a man named Mark Siwiec... He was my landlord while back, and he was AWFUL. I ended up calling the cops on him a few times, and he made my life a living hell... Just forwarning.
I wish you all good luck and congrats! I hope you enjoy Rachacha!
