Do the massage rooms have doors (or curtains), and do the walls go up to the ceiling (or there is a gap)?

I'm asking because I've had a recent terrible experience at 47a Alexander St, Crows Nest, where the massage room is 2 massage tables in one room divided by a curtain!
Had the misfortune of hearing the guy next door getting his rocks off --- and the sound was his and not the girl he was bonking.
