Located in the French Quarter, the Hotel Monteleone, a New Orleans landmark since 1886, is only one block from the city's famous Bourbon Street. It is also among the most famously spooked properties in the country.
In 2003, the International Society of Paranormal Research spent several days at the property. During this time, more than a dozen encounters were documented by the team, including one with a friendly toddler named Maurice Begere. It is said that he died from a fever in the hotel while his parents were at the opera; after, his parents returned to the hotel often, hoping that he (in spirit form) might visit them. Guests have reported seeing him near the room where he died on the 14th floor.
Guests and members of hotel staff have also documented the restaurant door opening and closing while locked and an elevator stopping on the wrong floor, leading people to a hallway that houses the ghosts of playing children.
Oh, and you'll want to think twice before greeting the housekeeping crew. A maid known as "Mrs. Clean" reportedly haunts the hotel and once told paranormal researchers that she stays because she wants to ensure high standards when it comes to hotel cleanliness.
