Looking for 2 BR apartment for April to July 2012 near Stanford Univ

I will be staying at the Stanford University for a 3 month sabbatical leave. I will come with my family (2 adult, two children). We are, therefore, looking for a (if possible furnished) 2 BR apartment/house from mid-April to mid-July 2012. Close proximity to the University Campus (biking distance) would be wonderful.
We are quite flexible with the arrival and departure dates, so please feel free to contact us if the rental period needs be moved by few weeks.

Best Wishes, Dieter
