Stayed in the Adelphi for 2 nights in September, regardless of all the negative comments.
I found the hotel charming, and the staff were very welcoming and accommodating.
My room was on the 4th floor, and not the alleged haunted 3rd floor.
The room itself was huge, as was the bathroom, both had been refurbished recently
.
My only gripe was that the bed and pillows were both quite hard, so not a great sleep both nights.
On my last night I walked through the lobby where I was confronted by 2 homeless women sat in the armchairs, asking for money. The guy on the desk could see this, but unfortunately did nothing about it. Overall, for £50 per night, you can't go wrong.
