There has been quite a discussion about Aerofan in the Spanish forum section, with widely varying opinions. I have no personal experience of them but see their planes flying a lot from Cuatro Vientos and they all looked well maintained from the outside.
I personally did my PPL with aeromadrid and was very happy with them, and am slowly continuing the modular course through them. The only thing I'm not sure about is if they do FI courses in English.
If you do come to Madrid to do it, I'd be happy to meet up for a beer anyway
