Plenty of London's hotels boast ghosts.
There's the Grange Blooms Hotel, near the British Museum, claiming to be haunted by the ghost of Dr John Cumming, an eccentric minister who had a bit of a fixation on apocalyptic prophecies...
Or the Georgian House Hotel, where the noise of children playing and banging doors has been heard, despite there being no children in the hotel; as well as unexplained icy blasts of air; and voices, laughing and footsteps heard where no people are present.
Perhaps you prefer your spooks have a celebrity pedigree? The somewhat shy ghost of actress Lillie Langtree is said to haunt the restaurant of the Cadogan Hotel at Christmas.
Then there's the super-luxurious Savoy, which features not only the ghost of a young girl, but also a ghostly lift.
Check into room 502 on the fifth floor for a chance to see the mysterious apparition of a lift controlled by the ghost of a girl who died in the building...
Surely London's most haunted hotel, though, is the Langham, which apparently features not one but several ghosts, and where strange goings-on have been known to terrify even the bravest guests.
Ghosts at the Langham
There's the figure of a man in military dress, who stands by a window on the fourth floor, said to be the ghost of a German prince who jumped out of the window before the first world war. There's also a ghostly butler, still trying to attend to his guests on the third floor.
Then there's the ghost with a gaping wound in his face, who tends to loiter in the corridors... oh, and the ghost of Napoleon III (a former guest) is said to haunt the basement.
But the most common ghostly sighting is a man in Victorian evening wear in room 333. He appears during October.
The legend goes that a doctor killed his new wife in that room, and then took his own life: it seems he is unwilling, or unable, to leave.
In 1973, James Alexander Gordon, a BBC journalist staying in the room (the hotel was once owned by the Beeb), woke one night in October to see a fluorescent ball of light turning into the shape of man, with the lower half of his legs missing.
Hovering above the floor, the ghost, in extravagant Victorian evening dress, stared at Gordon with vacant eyes (do ghosts have any other kind?) and opened his arms to walk towards him... Gordon fled the room.
Other reports in the intervening years have supported Gordon's story.
Recently, the England cricket team hit the headlines, when they reported strange goings-on at the hotel.
During the 2014 test, some members of the team said they were having trouble sleeping in their rooms; some of their wives even refused to stay in the hotel.
England bowler Stuart Broad recounted one experience during his stay that forced him to move rooms in the Daily Mail:
It was so hot in the room, I just couldn’t sleep. All of a sudden the taps in the bathroom came on for no reason. I turned the lights on and the taps turned themselves off. Then when I turned the lights off again the taps came on.
It was very weird. It really freaked me out. I ended up asking to move rooms.
Bealey (Broad's girlfriend) was pretty spooked, too, and I know Moeen Ali's other half won't stay there because she's so frightened of the ghosts.
Ben Stokes has had some problems sleeping as well. He's on the third floor, which is where a lot of the issues are. I'm telling you, something weird is going on.
In the end, Broad went to share with his teammate Matt Prior, who had a twin room.
