Acemassage lists working flats which usually have one or two workers each day and a "maid" to take bookings. They don't really have larger parlours in London like they have in
some other cities. You can DM me for recommendation because not allowed mention names of places on the forum.

i think the run of the mill parlours have all gone from London now
I worked in one for a couple of months when I first started but it has closed now
Its a bit too much for me working in them places
