Just finished a 2 nite stay at the Grand Hyatt Jakarta, was upgraded to the Premier suite. It was very nice, with a impressive jacuzzi tub, and all the complimentary fruits and chocolate from the C restaurant.
The club lounge is also very cozy, and from the suite, you can take a nice stair down to the lounge. The food was pretty good too, though not as impressive as GH Hong Kong, but good enough for me as dinner.
