What Cavok say might be correct, but just try to give them a call or visit their premises (better) if doing a ppl with them could be in your interests. Sometimes website creation are made by people who don't have a clue about aviation matters and such errors, as the one pointed out by cavok, could arise. If you call them, ask about their instructors, how they could sell a ppl with a cheaper price than what it is the actual average price in spain for a ppl, how many aircraft they have, if they own or have a maintenance organization locally or they need to send their aircraft elsewhere, what is the rate instructor over students, how many students they have already trained and what it has been their pass rate, try to talk with some of their students and ask for some feedback, last but not least ask if the course payment is in full or pay as you go and anything else could pop up in your mind. If their answers are satisfactory, they have good feedback from their students, they accept pay as you go and you have a overall good feeling, might be ok going there.
