Well, the ground school notes are appaling at Jerez. Indeed the majority never get used and most students end up using Oxford's to pass the exams.
Its worth investing in a pair of headsets, the one's supplied in the aircraft are pretty much the bottom of the range and are left sitting in the sun while being transferred from sweaty head to sweaty head.
And as for the airspace, it has its plusses and minuses as does anywhere, but the hot weather comes with as many problems as does the bad UK wx.
Don't be lured on what you see of the grounds, and the accomodation, that won't get you your ATPL. Oxford may not be a pleasure paradise but they've got the basics right at least.
