Look at ALL the empty space in where you live. Under the couch, under the bed, etc. Look UP, don't forget about the 3rd dimension of the 3d, even if it's just shelves up high in the closets (not that you need to access everything on a daily basis). Another thing to look at is off site storage (think small storage closet......not bad idea to prepare to lose primary house and still be able to function). Apartment living is hard from a preparedness stand point, but it's not impossible. Do you "live" in your apartment or do you eat/sleep in your apartment? Prepare accordingly.
