Tough question to answer...how much do you want to spend? Unfortunately the local market determines what is "reasonable rent." I also found last year that the listed price is actually the price for that special or that day; rental prices change for some apt's every day based on area availability...full exploitation of supply/demand.
I live about just a few miles from the Nell Woodruff bldg (where the Emory Dept. of Nursing is located). There are so many choices in the close Emory area, it can be just overwhelming.
I chose Post Properties; they have around five complexes in the immediate Emory area (approx. 7 miles or less). If you tell them you are going to attend Emory, tell them you are a graduate student; some of the agencies won't rent to undergrads.
We can split the referral bonus.
