I think most people flying reasonably seriously VFR around Spain use the Jepp "VFR/GPS" charts.
They are not perfect but they give you a consistent presentation across most of Europe.
I would use them for their entire coverage area, except UK and France both of which have IMHO better alternatives (the 1:1M SIA ones for France, not the very pretty but silly IGN ones which only go to 5000ft)
