I checked in at night around 11:00. As soon as I entered the room, my personal SOP was to check the cleanliness of the bed. And wow, the sheets looked like they hadn't been changed in months. There were many stains that would have come off even with a regular wash. The sheets had only been straightened, not replaced. I immediately called the front desk to ask for a replacement sheet. The replacement sheets were so clean and white, they looked so different from the previous ones. Please, please, have the manager or supervisor check the housekeeping work every now and then. As a mother, I'm very familiar with sheets that haven't been changed for a week. This wasn't even a week, it must have been more than a month.
