How is this a Sheraton hotel?
The hotel is total disappointment. It's supposed to have been recently refurbished but it looks dirty tired and unmaintained. The Staff are scruffy and, with limited exception totally unhelpful...very un-American. 
As for the rooms, I have never encountered such poor facilities in any Sheraton anywhere in the world. As a student I have stayed in fleapit hotels in Paris that were more hygienic and more spacious. The bathroom was so cramped I do not believe they were designed for adults. Why, I would, ask have a bath tub which isn't the width of a persons shoulders and then hang a shower curtain inside the bath so that it is impossible to take a shower and not get cloaked in a cold shroud of unknown cleanliness throughout the whole miserable experience of taking a shower.
We had a twin bed room but each of the beds was so small that if pushed together they might have made one decent bed between them.
When we checked in I was told the room had a rooftop terrace view....We had a window onto the roof alright but there was no access and there was a full height parapet with an air-conditioning unit on it that meant that if you opened the window you had the hum of A/C equipment to keep you company. 
I asked for a bigger room with better facilities and was told that of more than 400 rooms there was nothing bigger or better...unbelievable! Apparently the scale of the rooms is down to San Francisco being a "small city" what absolute tosh.
We booked a room with breakfast included. This was a complete waste of money. On one occasion the breakfast sausages we very clearly from the day before and totally inedible. The staff in the dining area didn't clear the used dishes until requested to do so and then in a rude and off-hand way.
I will never ever go back to this hotel, not even if I was actually paid to stay there and would advise anybody thinking about booking to consider any other hotel and I mean any other hotel. 
Myself I am not sure I will ever stay at a Sheraton again.
