I always recommend Thai London to everyone - they provide the best massages! Really deep, and the masseuses are trained in various techniques. Settings are fine, and relaxing, and they have heated massage beds which is lovely.
I have had 4 massages from here now, each with a different person, but each time its been brilliant. The only thing I would say is that they are quite strong/ firm massages. For me, this is perfect, as it really gets rid of all the tension and knots - great value for money.
However, for those people that like really gentle, super relaxing massages, that are not geared towards tension release - they are better off going to a beauty parlour-type place.
