If you want money, then either restaurant le wow or the pokemon league.
If you couldn't care less about money and don't want to do any work at all, throw two pokes in the daycare, go to the center of Lumiose on your bike, and stick a penny in the analog stick. Then go to sleep (IRL). It takes roughly 15-18 hours of this for the pokes in the daycare to hit 100.
I do then every time I go to sleep for some free and painless levels.
Also (Don't know if this works, I do it for good measure) give the pokes in the daycare a lucky egg each. --- FC: 1220 - 7215 - 6038 IGN: Apostle Ghost. Please add me!
