I havent heard of a "parlour" as in pay on the door and by the service.
However I have visited a whore who has advertised on AW at a flat on Jenkinson Grove, just off Harris road in Armthorpe.
Only met once, was a romanian girl, thin, moderately attractive but never offered the services advertised and was a rush job, few months on since then I have text 2 separate eastern European girls who gave me the same address but when I realised I never actually went any further having the bad experience the first time.
They usuall advertise on AW or viva but there not a permanent fixture, I think its possibly one of Sergei's property's that maybe he puts to good use while its vacant or not enough room in hotels?? Just an idea
