Huge disappointment
This was my fourth stay at this hotel - my wife and I had always enjoyed the central location and found the hotel more than adequate for the price. However this time we were bitterly disappointed. On entering our room we found that the closet door was stuck half-open, one of the bedside lights was out, and there was only one bathrobe. I called down and they sent a handyman up to fix things fairly promptly. This had already put us in a bad mood for what was supposed to be a stress-free weekend getaway. I started to notice other details about the room - there were stains on the carpet, the drapes didn't close all the way letting light in at dawn, fixtures were loose etc. Just a general state of disrepair that we would not expect from a Westin hotel.
Admittedly they did comp us a breakfast, but that was the least they could have done under the circumstances. We went to the bar for a Happy Hour drink. Even though there were only 4 or 5 people at the bar and they all had drinks in front of them, the barman cheerily said to us "be with you right away" - then disappeared for five minutes. If he had been busy we would have understood but we didn't want to wait, so went elsewhere for a drink. There's plenty of competition in Downtown San Diego so we soon found somewhere that did serve us right away. Next day we asked for a cup of tea to go from the Aroma cafe in the lobby. The lady who served us again disappeared for five minutes, then came back with the tea and marched us over to the bar across the lobby... where she took another five minuted trying to understand the complexities of how the cash register worked! 
After the maid had made up our room, yet again the second bathrobe had mysteriously disappeared. Add to all this the $32 a day parking fee and the $12.95 internet fee and we did not feel we had a good deal at all.
We will not be staying at this hotel again. Although we are Starwood "Preferred Guests" we did not feel like we had received any kind of special service - in fact it seemed on occasions that we were made to feel an inconvenience to some of the staff. There are dozens of hotels in this area and next time we visit San Diego we will definitely try another.
