Madrid Teacher
The madridteacher.com website was created to help promote Madrid-based freelance teachers and to help them find private students. The teachers represented on the website include bilingual English, German and French teachers who teach in small and mid-sized companies, academies, schools and with private students in Madrid. Some of the teachers also offer translation services. All the English teachers listed on the site are independent, and they are all contactable directly from the website.
Additionally, there is a page with details of teaching vacancies in the Madrid area, plus a small but useful collection of articles on living and teaching English in Madrid, written by teachers who have actually lived and worked in the City.
There's also a section with profiles of some of the language schools in Madrid, handy for newly-arrived teachers.
