Take a look at Aeroclub de Catalunya. I have been myself to complete my PPL and was really really impressed. Rather than just feel like 'another student' you really are treated properly. The people could not do enough to help me and I really felt special! My instructor hiding round the corner ready to spray champagne all over me after my 1st solo was a particular highlight. It may not have the flashy website of the larger schools but this shouldnt put anyone off what so ever.
