central park is a good choice, but i'm not sure about the price. another friend of mine (works in the airport too) pays 8 million for the rent only. + maintenance and electricity
...other option is taman anggrek , it's an older building, so hopefully the price might be lower.
will you go to the airport by car ( driving on your own, or by driver) or by cab?
or if you dont want to get stuck in the traffic, CBD apt close to emporium pluit is also an option . you will have more food choices there .. but the location is quite far from central ( where the party usually is)
