True, it's located near Leiden, where I live.
They have excellent research programs, exciting projects and great working conditions (salary and benefits).
It's full of international people and close to an international school (for those moving in with a family).
I'd love to work there, though it'd be an evil commute for me (I'm in Ede). I'm even subscribed to their jobs mailing list. I haven't seen any software developer jobs come up, though. :(
