Legend says that once upon a time the landlord of this guest house had fallen on the hard times and, desperate for money, he rented the house to a cloaked stranger for one night only under the condition of complete privacy.
Like in any good horror movie, someone did the exact opposite of what they should have and looked through the keyhole into the room on the third floor where the party was raging. The next morning, the peeping Tom was found pale and gray-haired. Last thing he managed to say before dying was that he saw the Devil getting married.
Guests can still rent rooms at the house and hear the clinking of glasses at the diabolical party, but should keep their eyes on their own keyholes if they want to survive the night.
