Teaching House CELTA course (Guadalajara)

Hello all!! I'm looking for some advice. I'm looking at doing the CELTA course in GDL with a company called Teaching House. Does anybody out there have any experience or know anybody that's done this course? I really want to find some people who have done this course and get their view on it as it's an expensive course but something I'm really wanting to do. I will then be wanting to teach in GDL! Any help much appreciated. Thanks in advance! :)
