Late by one day: $50 fee, and they only accept a money order.
Later after that? $10 a day until you pay.
No exceptions. Not even if you thought they weren't open on a Sunday which happened to be the 1st. It's not like they could've deposited my money until the following monday, anyway, so why punish me? Greed. Free money. Blind policy. Take your pick, but don't rent here unless you're 100% sure you'll never be late on your rent, not even by a day. Or you don't mind blowing an extra $50 on rent.
Oh, and the gym sucks. Smelly, suffocating because there's no ventilation, and half the time the machines are broken down. I tried to get a refund for my gym key (Yes, it's not free access), but nope. Fairness doesn't occur to these people, just rules.
There are much nicer options all around, even I think just across the street. A friend told me they were more forgiving, but double-check that for yourself.
