We stayed at this property over the weekend for 2 nights. The property is very well located right at Union Square - with all of the shopping / dining choices in the area. Property is currently undergoing significant renovation (I was told that rooms on floors 3-14) have been renovated. The unrenovated rooms are quite dated - we were given a room on 34th floor (the top floor of rooms) due to some mixup with the bed type in the reservation (had booked a king room - but was allocated a double perhaps because of the modification reducing the stay by one night). The Grand Club is on the 32nd floor is decent with pretty good choices of food; however, the space is a bit small and can be very crowded at times (not over the last weekend since the hotel was sold out due to a convention in town - so perhaps not as many with GC access in house). Overall, I would rate this property as good with good location but certainly not a top property either in San Francisco (Starwood actually has better properties including the LeMeridien which was the Park Hyatt before) or the Hyatt chain. It is a large convention / tourist oriented property which certainly not necessarily bad but not a "top" luxury property.
