Pretty good
We stayed here for one night as it was close to the airport. I guess I had it in my mind that the Sheraton hotels were amazing, maybe I built it up too much in my mind but this place was just okay really. 
In terms of price it's quite expensive to stay here, the rooms don't really match the price though. While they are a very large size and the beds are comfortable they seem a bit old and second rate, not the usual Sheraton standard. 
The bathrooms are old and quite small, our shower got clogged and we had to call house keeping. Also, someone had been smoking in our room and it had to be deoderised by house keeping.
Room service is very average, I wouldn't really recommend eating here, you're better off to catch the trolley cart service to manhatten beach for food. 
The concierge guy was bored, uninterested and made us feel like we had done something wrong by speaking to him. 
But overall it's not a bad place to stay, just didn't feel like it lived up to the amount of money we paid for it. I actually thought the Ibis airport hotel at Gatwick London was far better than the Sheraton in LA and it was a LOT cheaper.
