It's a little bit tricky to find. Don't rely on google maps - they will send you to the other end of the street and you can't get through the middle bit easily as it's a massive building site.
Look for the Globe Pub, and then go past those shops and the clinic is tucked down the side of those.
The therapist was nice, and the treatment was ok. I was trying something new, but it wasn't for me. I prefer hands on massage to machines. The machine is a bit noisy and mechanical and the pressure doesn't vary as much as it does in a normal massage.
