I can highly recommend FTE Jerez. Definitely not the cheapest but very good training and they have links with lots of airlines which can make getting a job easier once you finish. They also do accommodation and food which is nice because you don't have anything to worry about except training (the canteen is a bit **** and is the main source of complaints from students but honestly it's fine and it's nice not having to worry about cooking or going out after a long day)
