I would suggest finding somewhere other than the Loop to get an apartment. It's a great place to go out, but there are some pretty significant issues with crime in that area. Central West End, Clayton, Brentwood and Maplewood are all decent areas to get a place. CWE has lots of bars, etc. and is somewhat less questionable than the Loop, although you have to watch out pretty much anywhere in STL for things like car break-ins.
