I stay at this hotel every time I visit San Francisco. I stayed again in mid-February for four nights while attending a conference near the airport. I've checked a few rooms here, including 525 (where I stayed in mid-Feb 2012) for bed bugs and it's always coming up clean!
The main noise problem at this hotel is *not* planes, it's the new shuttle buses that were rolled out in early 2012. They make an extremely loud backup noise that's enough to wake up a heavy sleeper twice per hour! Prefer rooms at the back of the hotel!
