I went there recently. booked an hour with Helen.
When i got there Helen wasn't working but another lady, i can't remember her name. i asked if she was Helen and she said no, lots of different girls work there on different days she said. Its one massage room in the house as you come in, so they must rotate.
1 hour was £40 asked about extras and it was a £100 for topless and HE, nothing else, which i politely declined and said i would just have a massage.
She leaves the room to deposit the notes and comes back and offers 1/2 hour massage plus HE for £40 which i agree to.
So i guess if you want to see Helen, and if that is who the OP saw, then best to request that when you book or find out which day she works.
