This place doesn't have the luxurious ambience of a spa but that is reflected in the prices, and the massages are top notch. I've had the thai massage many times and it's always excellent. One tip for the business would be to remove the loudly ticking clock from the room, it detracts from the otherwise relaxing experience!
I recently ran the Brighton marathon and a friend recommended I go to Thai London therapy and i have to say it was a great choice. The women who gave me my massage really catered to my needs. I will definitely be coming back- highly recommend this place
