The route to the ASCL with Google maps and Street View

Disclaimer: the actual traffic situation may change. 

Take the exit 'LUMC' out of the Central Station. With your back to the Central Station, turn left, and walk towards the LUMC building (Universitary hospital).

Before the hospital, turn right and follow the Albinusdreef.

At the end of the road (Albinusdreef) you will see the Pieter de la Court -building on your right. Take note that the current, actual situation is rather different from what you see in Google maps, due to recent developments in the area.
