It's all up to you. If you find that you can study at home with a bit of noise in the background, then getting a roommate is a pretty good idea (from a financial standpoint at least). Also, you're never more than 30 seconds away from the library (and 5 minutes away from the public library). I'm married--and I believe Samiam is too--so take my opinion w/ a grain of salt, but I haven't heard complaints from other classmates who opted to live w/ roomies.
As far as safety is concerned--I wouldn't think twice about it. It's as safe as it gets. The on-campus apartments are in a gated community and you're literally ON the campus. No one is going to jump you here.
And what Samiam sad about the furnishings is absolutely right. I would also note that they're really lenient about what you do w/ the place ie: holes in the walls, hanging stuff, and the like. Hope this helps.
