I've skimmed up this thread a bit but can't find details. Perhaps it was another thread where somebody mentioned that directions to one lounge are well indicated and that the other lounge is hard to find.

I'm E+ flying in J in a few days (connecting from BCN) so it shouldn't really matter (apart from preferred the less busy lounge if possible). Anybody care to comment about finding the lounges? I'm used to just arriving "clean" at Ataturk and almost auto-piloting my way to the lounge...
