I am originally from Leeds before moving to Canada in the 1980's. We have recently been staying in this hotel when visiting family. It is basic but as others have said the rooms are very 1990's. If luxury is what you want others have suggested Oulton Hall, although I have never stayed there.

My real reason for posting, however, is that I came across the following painting on a Leeds nostalgia website. The painting is from the Victorian era and the building on the left, with the Number One sign, is the building that is currently the Leeds Marriott.
