While not universally confirmed, the Sylvia Beach Hotel is associated with several alleged paranormal experiences, including flickering lights, unexplained noises, and the slamming of doors, sometimes attributed to the hotel's stormy atmosphere and spooky ambiance. The hotel's literary theme, cozy atmosphere, and unique author-themed rooms are often mentioned in conjunction with these anecdotes, with some guests actively seeking out or accidentally provoking supernatural activity by exploring the attic. Some guests have reported hearing unexplained noises, such as groans from the building or doors slamming shut. One story describes a guest who intentionally tried to stir up ghosts by whispering in the attic and subsequently experienced "very active ghosts" for three weeks.
