Could be better
Booked here via the sheraton website and got a good deal on the bay view room since they price match. However was charged full amount and after a few emails, this was sorted out.
Picked up from airport on free shuttle (although did have to wait for about 40 mins). Check in was smooth and easy and the room was an spg guest floor. Room was quite large with usual amenities. Decor was showing its age though. 
Wifi is payable which is not great for a business hotel and although there is supposedly 30 mins free wifi in the lobby, this was so slow, I gave up after 10 mins. Tried to book some tickets via the business center computers and used it for 7 mins but got charged for a hour at $6.95 since they have a minimum hour charge which is not really good. At least online flight check in is free.
Used concierge twice. First time for directions which were spot on and second time for some advice. There were no one at the concecierge desk and so tried the main desk to be told they cant help me but will contact theconcierge to come and speak to us. After 20 mins of waiting, I gave up and went into the city to find some information myself which is not what i expect from a westin.
Checkout was quick and easy. Our flight was in late evening and since check out was in the morning, I asked whether they have any showers rooms to get changed in and the answer was a resounding no. I have stayed in a lot of hotels in various places and they usually have a room or shower place but not in this westin. So after a hot day of walking, a 10 hour flight without a shower was not really nice.
Seems such a shame since this hotel could be much better and needs to be more customer orientated.
If i come back to san diego, will be looking for a different hotel even though i am an spg member.
