Here's what the e-mail from AirBnb says, "After Dec 7, the review period will be over." It is not yet after Dec 7 in the timezone of where the company is headquartered, and where the listing reservation occured. Terrible wording, becuase I wanted to ensure I left a review for this traveler.
Also, it's so hard to contact the company just to ask a simple question. This company doesn't care about its hosts at all.
