Mostly people will go to Indonesian embassy at 7 Chatsworth Road in Singapore by taxi … so this is how you can get there without a taxi :
– Alight at Outram Park MRT station, take exit A
– Go to the bus stop at the opposite
– Take bus 75, alight at Aft One Tree Hill
– Walk to Chatsworth Road which is at the back of the bus stop. You must go back walk where the bus coming until the 67 Grange Road Apartment (the building’s colour is orange). And then you can see there is a road behind – that is Chatsworth Road, you walk until Indonesian Embassy. Not too far only 10 minutes walk.
