By car, just go straight southbound on EDSA, go past cubao, but do not take the flyover infront of camp crame, you will have to turn left there at murphy/e.rodriguez, and to do that you have to make a U-turn past that intersection's stoplight underneath the flyover.
When on e.rod./murphy, just go dead straight, it's about 3-4kms till you reach Katipunan. From there, straight again and the road will wind down, at the bottom, you will already be in libis, just continue heading south, after a kilometer you will see 2dozen buildings to your left, that's already eastwood. Entrance is either at the Police station there...or at the Citibank tower.
