I just dropped few stuffs this morning. The SA embassy located in somewhere in west bay. From rainbow roundabout you go towards the west bay ... pass Intercon and Aladdin Kingdom. Before you go up in the bridge (cross the water) you turn left in the roundabout. Pass another 2 roundabout, you make a 'u' turn on the second roundabout. Then you turn right on the first right ... then right again, right again. You should be able to see the building with South African embassy flag on the top. You can drop anytime in the morning before the 20th of June.
