hey- i went to emory for my undergrad but i can still tell you about housing-
so the grad apartments are on clairmont campus and it is a shuttle ride away from main campus. the apartmentrs are really nice and still relatively new (built a few years ago) ..
for off campus- you can find stuff close to main campus but 1. it may be hard to find and 2. probably really expensive
there are a lot of apartments (highland lake, gables) near clairmont campus- where you could walk to to get the shuttle, but might be a pain, especially during the winter. they are cheaper than lving on campus.
another good thing about on campus apartments is that you don't have to worry about paying bills. you get internet. ther is a nice gym, pool, tennis courts, field all there.
