Mediocre at best -- very disappointed
And that's taking into account that it's nearly spitting distance to the air terminal at LAX.
The decor, furnishings and finishes are terribly dated. The air ducts are dusty. The place smells old. The televisions are old, and the bathroom is small. It's also in a very inconvenient location in terms of driving in/out. 
I've never stayed in a Radisson, but was hoping that Sheriff Marge Gunderson was right in FARGO when she said it was a "good outfit." Not so much...at least as to this one. I haven't finished my stay here, and already I know that I will want to stay somewhere else on a future visit. The front desk staff was charming when I checked in, but other staff totall disinterested in doing much for you.
I often stay here in the LAX area. I'd highly recommend the Sheraton and the Westin, and have heard good things about the Renaissance. The Radisson will no longer be on my list of hotels to use.
Happy travels, all!
