Below average for a Westin.
Of all the hotels in San Francisco to put my elderly mother up for her Bucket list wish to visit San Francisco, I picked the Westin because of reputation and the views. 
Man oh man, talk about murphy's law. 
I can't think of one day that went right. From the broken fridge, to the wrong room, not to mention the view of the bay I was supposed to get, turned into a view of the back of a bldg. 
to not getting the breakfast vouchers and then being charged. I didn't even have a car, but was charged for parking. 
The hotel itself is nice, the location - eehhh, but they DO NOT have their act together. 
Stay somewhere else, even if they do accept pets.
