"Is that mold" should never come up in a hotel room, even if the answer is 'no.'
This entire chain of hotels is designed to lure you in and fulfill its luring promises in the cheapest, most technical way possible. It's like some evil genie is granting wishes, or more likely a lawyer. Here are some examples:
Kitchen: No soap, dishes, cookware, flatware, or paper towels. If you want that stuff go to a Residence Inn.
Breakfast: It's from 6:30 to 10, but the coffee runs out at 8:30 and no, we won't refill it. Legally this is breakfast because we put out 6 packets of Quaker Instant Oatmeal on the counter, along with some Costco Nutri-Grain. That's all you get. Want real breakfast, get in your car and go to Tim Horton's down the street. There's no sidewalk, so you have to drive.
Never in my life have I used shampoo, even hotel shampoo, that made me touch my hair later and ask, "did I even wash this?" I guess they found a way to ruin that too.
That's to be expected from this chain. This particular location is awful. In the middle of a busy highway it is a pain to get anywhere from here, and back. There is no way to cross the street without driving miles to the end and turning around, so add 10-15 minutes to any and every trip you take from this building.
The money saved here is NOT worth subjecting yourself to the squalid conditions. If you're broke go to a Days Inn; at least they don't try to pretend they have amenities.
