There are better LAX options...
There is nothing wrong with this hotel...but there is nothing great about it either. The room we stayed in was pretty dated but the bed was comfy and the bathroom was clean which is really all you need in an airport hotel. The shuttle was efficient and the driver helpful with our bags, the only other staff interaction we had was a check in, and the staff member was polite without being over the top.
We also used the Hilton nearby on our return and found it to be a much nicer property at a similar price and would probably not stay at the Sheraton Four Points again.
