Hotel average, but complicit in restaurant rip off
The check in staff (Sparkle and another gentleman) were friendly and terrific, however we had such a poor experience with the hotel restaurant that it ruined our opinion of the hotel completely.
We ordered "Food to go" from the menu in the room (from the restaurant in the hotel), which listed salmon at $14. When I went to pick it up, they charged $18 for it. When I told the restaurant employee that it was listed in the menu in the room for $14, he spoke to his manager and after a really long time, returned and told me that his manager said that I must be mistaken (the manager didn't even bother coming to talk to me). I then went all the way back to my room, retrieved the menu and brought it back to the restaurant to show them. After another long wait, the employee did the right thing, apologized and charged $14 for it, since his manager was too busy and the food was getting cold. In the morning, we awoke to an adjusted bill for $1 (yes, $1 only) for a service fee for the salmon. So not only did the restaurant try to overcharge me initially, and then I had to go back and forth to prove that the restaurant was charging more than the advertised price, but then someone went to the trouble of getting the hotel to administer a bill for $1 for a service fee. I think this was the restaurant manager's idea of an insult, and it's a terrible example of customer service. 
This was the worst, but other things that tripadvisor customers may be interested in is knowing that while there is a separate bedroom (separated by a door) to the living room, which is great for families, the pull-out couch in the living room is awful to sleep on and feels like sleeping on springs with no cushioning. Being near LAX is a plus, but the walls/ windows are poorly insulated and the noise from the airplanes is very loud.
Finally, and perhaps this is standard in Hilton hotels, but when you arrive there are two bottles of water, a bag of pretzels and a couple of chocolate bars on the table. It is a wonderful surprise, but then there is also a page that is completely incomprehensible talking about Hilton Rewards points and that you need a certain amount of points in order to consume the food and water and it seems to indicate that if you eat the food and don't have the points you'll be charged, but it does not state it clearly. We didn't eat the food, but it was quite a disappointment to first see the goodies and then see that perhaps it was not complimentary. It seems like an underhanded ploy for the hotel to add charges to the room.
In short, we probably won't be staying at this hotel or any Embassy Suites because of the awful experience with the hotel's restaurant and the hotel adding a charge after the restaurant greatly inconvenienced us.
