i am Greek and i love my country for a million reasons but i would never go do any kind of training (or studies) there, mainly due to lack of organization. and that is a general issue on almost each and every aspect of our society infrastructure.
im glad i ended up with the States solution. at least here if u r focused motivated and work hard u will make it. in Greece unfortunatelly it does not depend on u only.
of course thats my opinion.
good luck!
