"Throughout the stay, Lord and Lady Carnarvon will immerse the guests in the rich history and heritage of Highclere Castle with a private tour of the castle, the Highclere estate," the Airbnb listing promises.

Applications will be accepted starting on Oct. 1 and those striving to be chosen have to show they are "passionate about Downton Abbey" in a message that should accompany the application. The most creative will win, The Guardian reported.
