Hilton LAX (just down W Century Blvd from LAX), and the nearby ES LAX (just off W Century) should be the two closest properties.
The ES LAX South, DT Club El Segundo, the HGI El Segundo (all found south of the airport) and the HI LAX (to the east) are all also within fairly close proximity to LAX.
I personally prefer the HGI, and a Search for this property in this forum will yield abundant information concerning this property.
