Wat Sorn Thawee is in Chachoengsao. I understand it teaches Mahasi style and the accomodation and environment is a good standard.
“Peace is within oneself to be found in the same place as agitation and suffering. It is not found in a forest or on a hilltop, nor is it given by a teacher. Where you experience suffering, you can also find freedom from suffering. Trying to run away from suffering is actually to run toward it.” ― Ajahn Chah
