Purchased a multi by as I have had these treatments before when they were based at the Wardorf Hotel. As I had not been for a while Suzanna asked how high I wanted the temp initially, always better to start medium and when she comes in to ask how you are, then you can request to increase or decrease. Finished treatment with some some water to flush out the toxins. The issue which is a minor one was the bathroom/toilet was out of order and during the course of three tretaments was still out of order. Still the treatments are interesting and the staff are helpful and friendly. Go on give it a try!
