If you think searching for an apartment in SF is a nightmare, those looking for commercial space have it worse. There's no easy way to figure what spaces are even for rent, and commercial real estate sites leave, well, something to be desired. Billing itself as the alternative to that "clusterF@%k" (ahem, this was in the pitch), 42Floors puts commercial rentals on the map in a clean, simple way. We've taken a peek at the website and think it's quite nice, even if all the listing pictures are using a little too much "Ken Burns Effect" for our tastes. Enjoy.
