The W SF building is also never going to be able to hold a candle to the glory day Ws, however, there are some positives. First, wifi is free and reliable in the lobby, which stretches over two floors -- this means people still use the W lobby as a meeting spot. Second, the Thirsty Bear is right across the street. So, if you stay here, ditch the sad W bar and head over to the Thirsty Bear for drinks and tapas. And finally, now that many of the rooms have been retouched, try to upgrade like mad. If you are SPG Gold, or a smooth talker, angle for high floor rooms, corner rooms, and if you are really suave, get yourself upgraded to a suite.
All the redesigned high level rooms are far more comfortable than they were a couple of years ago, good luck and see if you can become a "room upgrade artist".
