I worked for Bristol School in Portugal for a year, and would like to warn teachers to stay away from this school. It doesn't pay what it promises and the apartment arrangement is a scam. Management is incompetent and the people directing the school are extremely petty. They are nice for the first few months, but rip you off your money behind your back with confidence. A lot of miscommunication and misinformation which ends up always affecting the teacher and benefiting the school. They hire teachers often, because all their teachers leave after one year or even less than that (no wonder!). You might see their add disguised as : Instituto de Linguas, Porto Region.
