I booked a Thai massage at my place with So Thai Massage. It was a real Thai massage. I told the therapist I want a strong massage and she did exactly that. I was very impressed. Maybe it was not quite a real spa experience (as it was not in a spa) but it was still a spa-like experience (the therapist wore a uniform and was very polite and professional). It was not cheap but was good value for money given that it was a real proper Thai massage with a therapist who clearly had many years practice, rather than what I have had before in London which didn't really deal with knots and generally left me unsatisfied.
