For a thai massage that really works from people who are professional, through, honest, highly knowledgeable and truly care about the pain you are in and how to tackle it, go here. I always do now. And you can trust the therapists to know what is best for you, which is particularly useful when you need a particular firmness and position of pressure to make it right.
I always come to Baan Thai for my massages. Pregnant or not. Every time I visit I get a warm welcome and leave feeling so relaxed. The pregnancy massages are wonderful. Extra pillows are provided for comfort and the therapist always ask what areas they should focus on.
