Location does not make up for service issues
The location on Union Square is terrific. However, fighting the traffic off 3rd Street and then Geary Blvd is a real challenge in the afternoon. Then 10 more minutes waiting for a spot in the hotel garage to leave the car for valet service, at $ 51.00 per night! 
There was no offer to carry our two bags from the car and two people to service check-in on a Saturday night seemed well understaffed. The clerk was very pleasant and directed us efficiently towards our room. Again, no offer to assist with our bags.
The room was on the 4th floor and after a wait for the elevator we wandered down to find our room. I was disappointed to find we had a Post Street view in a very small room We had requested a king bed and got a queen. Since we had an event to attend and little time to waste, we accepted the room. The room was clean and the large closet was a bonus. We found the bathroom to be functional but hardly first class. One of the towel was folded but already wet sitting above the toilet. The vanity sink did not have a space large enough to hold a glass. The glass enclosed shower was small but would have been okay if the water would have gotten warm in a reasonable amount of time. The overhead square showerhead was unique and it did have a removable shower head also. The soap was inconveniently in a plastic wrapper that was difficult to open with wet hands.
Fortunately, I woke up early as our request for a wakeup call was either ignored or late. My wife wanted to make a quick cup of coffee and had to move the coffee maker to find an available electrical outlet. There was no line at check-out and the clerk was very friendly. We waited over five minutes for our car AFTER calling ten minutes earlier from our room.
I would certainly recommend the group stay at another hotel in the future.
