Help!

Ok so my apartment smells horrible! It smells like an old house combined with smoke. Nothing against people who smoke but the smell is horrible especially since it comes into our apartment and makes everything stink and makes me smell and feel gross no matter how many times I shower or wash clothes. I’m getting tired of it. We pay to much for rent to get this. I’ve called and no candles work, no warmers work, no house spray, nothing literally works! It’s driving me insane! We only have like 6 months left but I can’t take it any longer because I’m tired of rewashing clothes everyday or other day because of the smell. I don’t know what else to do.
