I think you'll like it. I can't comment on the lounges at any of the Hyatts I've stayed in San Francisco as I often don't arrive until 10 PM or so. UA28 arrives so late that I'm forced to spend the night here. HR Embarcadero seems to show its age more, but excellent location. SOMA was nice, but I didn't get an upgrade. GH SFO’s hard product is fantastic and reminds me of a hotel from Asia. The breakfast sucks though. GH Union Square is in a nice location and the walk from Powell Station isn't that bad. No more than 5 minutes. I’ll have more time in January 2023 and I'm thinking of doing some hotel hopping in San Francisco.
