If I may dissent. As lounges go, this one is newer, cleaner, and has a cool cool $15K coffee machine. There are little snacks during the day and little noshes at night. Lots of comfy places to sit and plug in and work. Breakfast is delicious and of high quality but repetitive. But miles better than breakfast at home.
The entire area is blighted and third world level disparity between have and have nots. Not many places in the world you can walk from a Four Seasons right around the block to a open air drug market/homeless encampment.
All that said my go to for stays in SF. I prefer this location to the emabarcadero or japantown hyatts.
Have fun down there. Probably best to go now as the AIPAC pow-wow used a big broom and swept the uncomfortable realities aside.
