Do you know Al Shaheen in Muntazah? - from there it will be easy to find.

If not...

Try this, from Ramada Signal, take the road C-Ring (facing the Airport), turn left at the next signal near petrol station (AKA American Hospital), go straight up to the signal intersection, when light goes green, go easy left and briefly turn right, go straight.

You will see the Hospital symbol to your left.
