A local friend of mine recommended this spa for good, legit massage while in Jakarta. It's basic and not fancy but the price is terrific and if you're staying at the Four Seasons or the Aston, it is a five minute walk.

Lumiere Spa is located in central Jakarta very close to main hotels and offices in the City. They provide a very professional and pleasant service for a much lower price than what you get in Spas at Hotels.
