Recommend a hostel in Kemayoran area (Jakarta)

I'm going to be in Jakarta for two exhibitions on the coming Tuesday for two weeks

The exhibition address is:

PT Jakarta International Expo
1st floor Pusat Niaga Building
Arena PRJ Kemayoran Jakarta Protected content

Is there anybody in town can recommend me a hostel at Kemayoran area and convenience to go the international Expo and near the bar?

Thanks.
