Great public spaces, Corner Suite = depressing and, just...icky...
I am a SPG Gold Member (I travel a lot for work and love it!). For this trip, I booked an Executive Suite (online deal via SPG web site) for business. They gave me a standard room instead. After a short wait they were able to find a Corner Suite. However, even though this sounds great (and most other Sheraton's Corner Suites ARE great), this one smelled musty, dank and the best word I can think of is...icky... (when the manager met me with the key to this 2nd room - he even commented that it was "musty" and did I want housekeeping to "spray it." I opted out of that masking solution. Anyway, it is not a very comfortable room overall.The worst part was the air conditioning, which not only sounds like a loud, rattling lawn mower in your room, but it also leaks (the carpet was wet - was nice stepping in that with stocking feet-yuck). When you turn it off it sounds like water torture (drip, drip, drip, drip...) dripping into the space/wall (I looked inside the wall vent and sure enough there was a puddle in there). I called and they were going to send engineering to fix the AC when I was away from the room working, but it was not fixed. Also, the room had an odd, very strong odor of cigarette smoke & BO upon my return. Again, ick. The bed was somewhat 'thin' and hard and there were no extra blankets. The tub water backs up to your calves when you take a shower (triple ick). I usually order room service, but the room was so dank and depressing and smelly and... icky :), I left to sit alone in the lobby restaurant. 
Positives: The Corner Suite is MASSIVE - and if you want space - that is what you get (albeit, not very comfy space). I have stayed at this hotel 4-5 times and the staff is always very pleasant and accommodating (when you have an issue they throw lots of points at you to 'fix' it - which is OK with me because I am a points hound, but I wish I didn't have to complain in the first place). Watching the planes land at LAX is fun from the room. The lobby is modern and bustling and the bar area is well laid out, which is a great place to people-watch, and although the service was sloooow, the food is decent 'bar' food. Starbucks in the lobby (but very long lines - out into the lobby - in the AM). Very easy to catch a cab at any time of day...
