I am under the impression that there used to be a place called the SIAI house in Santa Clara, which housed the SIAI Visiting Fellows Program. However, this post suggests that it has moved\is moving to an unspecified location in Berkeley. My efforts to find additional information were unsuccessful.

So, does such a house still exist? What is its exact current location? Does it welcome random visitors?

I ask this because I plan to be in San Francisco on 9-11 January, 2011 with a lot of free time on Sunday the 9th, which looks like a great opportunity for a visit.
