Feedback on local Language schools (learning Thai) (Bangkok)

Hello,
I am new to Bangkok, and I would like to qualify for the 6 months or 1 year ED visa, besides the (amazing!) opportunity to learn Thai.
I would like to hear some feedback from expats who might have been to the following schools: Pro Language, AAA, My Little Thai, Language Express ......

I am a French-Spanish teacher by profession, so I am learning very fast, hence I would like to attend just a few lessons ( my focus will also be on business projects...)
Thanks for your tips,
Christophe
