It's an established Polish outfit that used to be very popular a couple of years ago. It used to be discussed on another forum that saw better days too
I've been there a couple of times - last time about a year ago. It's a nice 2 massage rooms + lounge (waiting room) - basement/ground floor flat with a separate entrance in a converted house.
HR was always included in the price but if you wanted topless of b2b you'd have to negotiate with the girl separately.
They used to have some real stunners but I think they changed management and had some issues with the plod.
Good to see they are still going but cant say about their current standards.
