Nice hotel, good service
We stayed at the InterCon for a wedding in the LA area. Overall, we found the service to be very good - particularly the concierge and room service. As other reviewers have mentioned, this is a very corporate hotel, but it was well-located for our needs. 
My biggest gripe was that the hotel was lacking in maid service. We stayed three nights and only once was our trash emptied; we felt like they sort of phoned it in. If I were to stay there again, I'd be a little more active about making sure they clean all they are supposed to. 
The gym is pretty nice, but the women's locker room could use an upgrade - I was unable to use the steam room or sauna b/c it didnt get warm enough and the attendant said both rooms were already on thier highest setting. I've heard very good things about the spa treatments, but skip the steam/sauna. The pool is also nice, but nothing interesting. 
It was a huge help to have the car service that drops you up to 1.5 miles from the hotel -- this gets you to the Westfield Mall - which has a very nice selection of shops. It was a nice answer to constantly taking your car our of valet -- which also can get pricey w/constant tipping.
I would say the rooms are a bit dated, but perfectly nice. We stayed in 628, which has great light - nice balcony, but it overlooked the Fox lot - not terribly interesting.
