From the hospital main entrance, after you pass reception on your left, turn left and walk down the main corridor, taking an immediate right (before the lift).  Go down to the end of this corridor, following the bend to left for Radiology.  Take a right at the end of Radiology reception and you will see a lift on the right. Take the lift to the 2nd floor -- exiting, you will see double doors to ICU on your right.
