I remember that building! I used to pass it all the time going to the then Sunnyvale main post office at the corner of Mary and Maude (now, shockingly, an Apple building).

Thanks!

No prob. Not sure the safest way to get there, but I'd probably start by taking Stevens Creek Bike Trail to Evelyn ave and then maybe heading up Mary (which is a pretty busy street, so maybe there's a better way.) Strava might be a good app to check.
