Been past those shops lids of times and can’t recall seeing anything like a massage parlour.
Scouted it out today from the map location, couldn't find squat. Full marks for discretion.
I was tempted to call so flitted through the website and Miss B is also advertising on AW under a different number.
Didn't hang around too long as i think i was the only person who owned a shirt in Blackheath, and my own teeth.
If i get up there again i'll do some more hunting - website does say free paring at the rear but all ones i saw were P&D.
I think only Lidl has free parking so maybe that side of the cross roads.
