Airmed USED to be Spain's best Flight Academy for Integrated ATPL. Sadly, since 2003-2004, things have gone downhill a lot... I don't know how they are at the moment, but they did rehire some experienced people like the Head of Training (the retired head of training Iberia).
Adventia in Salamanca and FTE in Jerez (which has several ex-Airmed instructors) are still good options I believe.
Also there is Gestair in Madrid.
