Expensive, but nice
Stayed here for a conference. The room is nice and has a contemporary, funky feel. The water pressure was kind of pitiful (I was on the 9th) floor, but I think that was more about being "green" than anything else. Staff were all very helpful and professional, and the location is now very useful as there are a number of interesting restaurants around the area, as well as a Starbucks right next door. I particularly recommend the Pantry Cafe for breakfast, and Rivera or Rosa Mexicano for dinner.
That said - it's a fairly expensive property and the wireless/internet surcharge of $12.95 is ridiculously high given how poor/slow the connection often is. It's also an expensive cab ride from/to the airport
If you're conducting business in the vicinity, I think this is a good place to stay. If you're vacationing LA, you might want to look at all your options.
