Presuming you are seeking massage
with additional services there are a couple of options:
External Link/Members Only. Probably the best of the bunch currently. Not in the City Centre, out in Beeston. Quite attractive girls, good clean smart premises.
External Link/Members Only. City centre (Harrison Street, just off Vicar Lane, around the corner from the Headrow). Can be a bit hit and miss, quality of girls varies as does their level of greed.
External Link/Members Only undergone numerous name changes - Orchid, Tulip and currently called Suphawadee. Nice smart warm welcoming premises, once you have gone through the supermarket downstairs. Some nice girls, basic massage prices a bit steep. Cher who works there is a truly filthy slut but ridiculously cash greedy. Will do FS but demands £200+(!!)
There is also a massage setup in AZ Nails, further down The Headrow (opposite Argos). (Their Gumtree advert has expired). Poster in nail bar window has the phone number. Variable reports, seems they now have *mature* masseuses.
Bangkok Spa and Nuad Boran (either in Kirkgate market or their smart premises on Vicar Lane are legit (Nuad always have been, Bangkok have gone over to legit massages only)
