Harry Potter fans are clamoring to book a limited number of rooms at a central London hotel that were decorated based on the popular J.K. Rowling books.
The hotel rooms -- also called the Wizard Chambers -- have been decked out with potion bottles, cauldrons and "unexpected wizardly details," according to the Georgian House hotel website. "They have a gothic feel, very true to the spirit of Hogwarts."
Muggle fans, however, might have to wait to book a room. The hotel's website has been crashing after unexpectedly high customer demand, and calls are taking a long time to go through. A spokesperson at the front desk told CNNMoney the phones have been ringing off the hook.
The hotel is booking rooms into December 2015.
Georgian House hotel has been offering a couple Harry Potter-themed rooms for a year. But demand in recent days skyrocketed after some local ads led to a storm of media coverage.
The Harry Potter-themed holiday doesn't come cheap. One night's stay for two costs £209 ($340) and the price shoots up to £363 ($585) if you include breakfast, a special "Muggle Walking Tour" and tickets to a Warner Brothers Studio Tour that showcases the making of Harry Potter movies.
The final novel in the Harry Potter series was published back in 2007, but the popularity of the boy wizard persists.
In July, Universal Studios Japan unveiled its long-awaited theme park -- the Wizarding World of Harry Potter.
It's the second Potter-focused theme park from Universal -- the original opened in Florida in 2010.
Universal Studios Hollywood is said to be getting its own version in 2016.
To keep fans interested, author J.K. Rowling also recently posted a short story on her "Pottermore" website, which gives a glimpse into the life of a 30-something Potter.
