There have been previous posts comparing LAX hotels including the Renaissance.
I stayed there last November at a Priceline rate of $45 when the hotel was sold out even at rack rates of around $200, so I was happy.
I didn't use the facilities, so can't report on those. Our room was fine, almost certainly a standard room, and was quiet, which was what we needed.
Very close to car rental depots. Bus to/from LAX terminals.
I even got Marriott points on extras.
