Don't! Just don't! They are DREADFUL. My husband and I lived in one for a year and moved out as quickly as possible. It consists of two 12 x12 rooms, with the living room and kitchen being the same room. Your "kitchen" is a counter along one wall - no dishwasher, and you have a very tiny stove/oven. Walls are cinderblock or thin plaster, and you can hear everything from your neighbors. It's cold and dark, and there are only two windows. Oh! And our bathtub was so gross when we moved in, just from years of wear and tear, that eve after scrubbing it several times I never felt comfortable enough to lie down in it. Lastly, there are fire alarm drills about once a week - at all hours of the day - and you MUST leave your apartment when they happen, no matter what.
The only good thing about on-campus housing is that it's a little cheaper than living anywhere else. But it IS NOT WORTH IT. Moving out is one of the best decisions we made.
