I can give you direction using Salwa Road coming from Ramada Signal. Turn RIGHT at the Decoration round about (R/A), you will approach Al Waab Signal, ISF R/A, then another R/A, straight, then another small R/A. to your left, you will see a big white wall, then another wall of Kahramaa, turn LEFT at the street just next to Kahramaa wall. you will reach the end of the road which is closed but you can use the rough road on the right side. the long walled compound to your right is already the US Embassy.

good luck!
