Guests must sign a disclaimer to enter a hotel room due to its very high levels of creepiness.
Ye Olde Kings Head in Chester is said to be home to several ghosts who spend their time spooking out residents.
The structure is 401 years old and made headlines in recent months due to reportedly ghoulish activity, including a chair which allegedly began moving by itself, Cheshire Live reports.
There is one room in particular that is so deeply spooky that only experienced paranormal investigators are allowed into it.
Even then, professionals have to sign a disclaimer to spend the night.
Inside room eight is 'The Grace doll' who spends her time in a special glass case.
It is said to be the UK's most haunted artefact and a special camera has been set up to monitor the creepy little object 24/7.
Since it's arrival earlier this month, people are said to have been struggling to stay in the room, with some only lasting three minutes before rushing out.
Others have claimed their eyes felt like they were burning.
Paranormal investigator Danny Moss, one of the team behind My Haunted Hotel at Ye Olde Kings Head, said: "Since it arrived in January we've already had people really struggling to stay in room eight. It seems to really affect men rather than women.
"We've had men go in there and they can't look at it. They feel anxious and have to get out, struggling to last even three minutes.
"People are hearing the sound of three knocks which is meant to signify the mocking of the Holy Trinity. Some people have also experienced their eyes burning.
"That happened to me a few years ago when we kept it at Tatton Old Hall. I heard an entity say 'burn' and I said 'what?' and my eyes felt like someone was chopping onions.
"We've got video footage showing people really scared to go into that room and others with noises coming from it.
"There are a set of rules outside room eight, including people having to call out an audio disclaimer before they're even allowed in.
"Room eight is only open to experienced people. For people who've not done this before it could be dangerous."
The hotel has gained reputation over the years for its paranormal activity and has even featured on TV show, Most Haunted as well as Sky Pick's Paranormal.
It was bought by paranormal enthusiast Harry Achilleos 15 years ago and his dream has been to turn it into a top dark tourism destination, due to its spooky reputation.
Harry added that the Grace doll in the building has taken My Haunted Hotel to a "whole new level".
He has since installed a series of infrared cameras around the Grade II Listed building in a bid to monitor any unusual activity, which has ranged from eerie mists to poltergeist activity in the bar.
With many spooky artefacts on display - including a doll called Willow sat in a glass case in the bar.
Those brave enough can book a stay.
