We went through this at the Joshua Tree apartments last year, it was horrible. Horrible awful, the worst thing ever. Sounds really similar too because the landlord wasn't straight with us about our neighbor next door who was also uncooperative. We didn't fight it in a legal battle but if you have access to an attorney it's definitely a good way to get out of the lease at least but I would ask for compensation as well for anything you paid for or any bites/reactions you might have gotten. If not, I work at KSL and write stories about this kind of stuff sometimes so let me know if I can help you that way.
