Assuming that by "magic" you are looking to network for business opportunities rather than socialize and be a tourist, then you are probably better served by starting off with a scan of meetups and semi-organized gatherings that fit your needs and work back to a location from there. Since your schedule seems a bit open I would see if there is a major conference of some sort in the area that you want to attend. Arrive a couple of days before the conference to do a bit of preliminary face-to-face networking, work the conference, and then have a plan to follow-up in person with leads and related meetups and gatherings. Depending on what your company is doing, your are probably going to be better off looking at the Palo Alto & Mountain View area for housing -- there are hacker houses and extended stay hotels available, possibly some short-term rentals, and SF is just a train ride away. Most of the bay area tech scene is not actually in SF and being mid-peninsula will give you more options.
