Thanks for reminding me of one of the best 4 days aviating I've had in 20 years - would agree with all good things stated above. Hans spent at least a couple of hours briefing me about the area and airspace, with ideas, hints and tips, so I felt almost at home almost immediately.
I'd done about 10-ish hours solo in a couple of days and was a bit tired so asked Hans if he would accompany me in to Portugal - we had a long and interesting day to Cascais (near Lisbon) via Portimao.
The solo flights I did were North toward Cordoba and Seville, and to the huge mountains east to Granada. No ATC problems anywhere (though it was busy near Lisbon) and they were very friendly even during/after a self-induced partial radio failure near Granada (blush).
Highly recommended. I've some online photos if anyone's interested.
