Very easy to find and very close to Bethnal Green tube station.
The place looks ok but not immaculate: the floor was wetin the changing rooms (puddles like in a swimming pool), the tap i used to wash my hands was broken and the receptionist was polite but not smiley.
The therapist I had however was lovely and professional and the treatment was - as far as i can tell - well executed (it was the first time i had it).
I have been to more luxurious spas before so I can tell the difference in terms of client management and facilities but overall, the place is nice and for the price, it is worth it!
I would recommend the place.
