Jakarta is SUPER traffic city and you must pick the LOCATION first. My apartment is can not be more center. Not only easy to go everywhere but also 24 hours access with private security system and friendly.
The apartment has its own private swimmingpool, whirlpool, big roof garden, fitness center. A walking distance to resto, cafes, shopping from cheap to luxereous ones, cinema, museum, Tanah Abang whosesale famous market, anything you need. Couldn't be more central than this location.
