"Charismatic, but that's all...."

Charismatic, but that's all. They fail to call back for over a week at best, and if you dare put an offer in on a place they won't contact you until they've received a better offer from someone else. Also make sure you know everything you can do to hold a place, like filling in an actual application form and paying a holding fee beforehand, because they sure as hell won't tell you anything you don't ask about. And don't be fooled by their charismatic and seemingly helpful tone of voice, they don't care about you, no matter how difficult your situation.
