I had a Brazilian wax here, the service was ok though the girls seemed exasperated when I arrived.
The room (as with all central London salons) was tiny but they did a good job.
This is maybe my 4th time going here; it's sometimes great and others, not so much. On this occasion the therapist actually ripped a bit of skin off which is still healing. I didn't realise it at the time and I think if I do go back, I would request the one therapist that seems to be very good.
