Maybe process it where you are hunting, before you go home. Or at least partially process it. Bring a folding table, and use that to bone it out, put your meat in zip lock bags, and label each one so you know if it's from the hind quarter, shoulder, back strap, etc. When you get home you'll have a cooler full of boneless meat in zip lock bags, ready for further processing, if needed, which should be possible to do in your apartment, or you could just throw it in the freezer as is.
