Langtrees.. quite ok, got multi-national WL. saw couple Thais as well but went for an Aussie instead...
think i paid A$150 on my last trip last year.
nice big rooms with various theme.
called and check out from the personal ads, one korean student quoted A$200 for ST but didnt got for it.
there's another joint like Langtrees but somewhere near the Perth city in one of the houses. charges was $90 for massage and HJ. sorry cant remember address cos checked form newspaper and drove there.
