Most expatriates live in houses in South Jakarta, preferably near Kemang, but more and more live in apartments. It is rapidly becoming more of a buyers' market as the rupiah plunges in value and Jakarta heads towards an oversupply of top-end housing. Most deals are currently being negotiated in Rupiah, and even those that are nominally in dollars are at a fixed exchange rate bearing no resemblance to the real exchange rate. There is even a VCR rental in Kemang. There are some lovely houses too.
Gardens are a speciality.
The soil and climate are magic. You are also expected to pay around this much as a bonus at Ramadan. Sometimes food is included in the conditions, and sometimes not. It may include a travel allowance. Drivers are highly recommended because driving in Jakarta takes some getting used to, and they double as security guards.
