Lovely atmosphere and nice relaxing massage, I would definitely come again. The only issue was with timings. I called up to change my booking to 15 minutes later. When I arrived, it transpired that they had changed my booking to half an hour later, which meant I had to wait 15 minutes. The massage itself also ran over by 15 minutes, despite being quite specific that I needed it to finish on time. So, be wary if you're in a rush.
I had a great massage at Thai London Therapy. In particular the hot stone part of the massage was great. the only downside was being in the therapy room on the mezzanine which meant I could hear everything going on in reception.
