OUG is very very central. Now with access directly to KESAS via Awan Besar you can hit Shah Alam, Seremban, KL, KLIA very quickly. You want to go to PJ just use Old Klang Road / Federal Highway. School os there both Primary and Secondary. Kindergardens aplenty. Food wise spoilt for choice. Petrol Stations, CLinics, Convenience stores. You can go on and on. TESCO is opening up pn old klang road with mixed business ie. restaurants and banks and this will only see the prices escalate. The same size unit in Puchong is more expensive and further in with massive population moving traffic early in the morning, its like hell. With that being said, OUG is the last frontier of Kuala Lumpur as it falls with WP whereas Puchong is Selangor.
