Some nice features, but nothing seems to work
My wife and I stayed at the Sheraton Los Angeles for three nights during a business trip. We had been hoping that my Starwood Gold status would get us an upgrade to the executive level, which has happened occasionally at other Starwood properties, but we were happy to settle for a southeast-facing corner room on the 18th floor. This turned out to be a mixed blessing: the room was large and looked nice enough, but the view turned out to be nothing special -- the massive parking garage and some uninteresting sections of south Los Angeles -- and the two walls of windows caused the room to be unbearably hot. This was exacerbated by the weak and antiquated air-conditioning. Unlike 99% of modern hotels in which each room has its own thermostat and fan control, this one only had an on-off switch and a lever that went from "Warm" to "Cool". We followed the advice of the hotel staff and kept the curtains closed most of the day, although sitting in a dark room more or less defeats the purpose of having panoramic windows. But when I tried to work at the desk near the closed curtains it still felt like I was sitting next to a heater.
There were other technical problems as well. The water in the shower never went beyond lukewarm, and the water pressure was also very weak. A hotel engineer explained that the state and/or local governments had imposed "low flow" requirements on the shower heads and that the hot water had been restricted "so that you won't scald yourself." But the net result was that taking a shower was not a pleasant experience. And I don't recall having had this problem in other Los Angeles hotels.
Although fixing these big problems might require a top-to-bottom remake of the hotel, there are other problems that would be much easier to solve. The only drinking glasses in our room were flimsy disposable plastic ones; the towels looked like they had been purchased on a budget a few years ago; there was no safe in the room. 
On the good side, the hotel has a great location, steps from stores, restaurants, and downtown office buildings and quite near historic Los Angeles neighborhoods and attractions including the old Pueblo de Los Angeles, Little Tokyo, and Union Station. There's also a Metro station right across the street. The bed was comfortable and the large flat-screen TV was impressive. And we found most staff members to be pleasant and helpful. (Unlike some other reviewers, we found the Housekeeping staff to be hard-working and efficient. A couple of the reception desk staff were brusque and cocky in an urban sort of way. They probably didn't mean anything by it, but all hotels should give frequent refresher training in the Golden Rule.)
