Checked in a couple weeks ago for 4 nights and had a confirmed reservation for a terrace studio, when I checked in to the Autograph Lounge the agent welcomed me as a Platinum and upgraded me to a 1 bedroom premium view in the Chelsea Tower without request.
She Offered 4 bottles water as well.
Coffee machine is Starbucks so super slow but makes great coffee also an urn of drip Starbucks available in the morning. I was not expecting much and the room upgrade made our stay really nice.
