Just finished a three night stay at the SR in SFO. After trepidation on the board and a bad SR experience in DC, I almost canceled, but I’m glad I kept it—I was impressed.
Checkin was instantaneous, though there was no one to take me upstairs (not that I need it, I can pretty much handle my own bags through much rougher situations than a St Regis elevator.) Upgraded to a 02 room, which was large for a non-suite and well laid out especially if you like modern décor (which, I’ll admit grew on me). By a small miracle, both the cordless phone and the bedside console seemed to work (even though there was no iPod cable for the console)
Staff were well intentioned and gracious. Concierge handled requests (of average difficulty) with speed and a smile. Doorstaff (when there, I got back REALLY late one night and there was no one around) were efficient and curious (Welcome back sir, did you have a good evening?)
Didn’t get a bill under my door for checkout, but one phone call remedied that in about five minutes.
A few nitpicks (and I’m being picky here).
*) The butler. I never actually met the butler, and I’m not convinced that s/he exists. Whenever I rang the butler button (more on that in a bit), guest services answered. That’s totally fine, I don’t mind the service express concept (so long as it works, which it did here), but if it’s service express, than call it that. Butler service is something slightly different, and I didn’t actually come across said butler at any point. . . ..
*) Lighting. My room was dark at night. Not a big deal, but I have work to do when I get back to my room, and I’d like some light to do it to. Yes, there was a desk lamp, but the complete lack of overhead lighting just led to a shadowy feeling around the room, one that combined with jetlag to keep me from getting much work done. Service Express (sorry, Butler) eagerly sent up a bellman with another lamp, which while helpful, but didn’t do a ton to solve the problem. A floor floodlamp would do wonders. . .

Two small nitpicks at the end of an otherwise excellent stay. I’ll be back.
