It was a great place! Real classy and clean. Bed was really comfortable and the sofa bed was easy to set up. It's a bit of a walk to the strip as you have to walk through MGM Grand first, but it was good for our purposes.
The only small complaint I have was how hard it was to get the keycards to work to operate the lift and open the doors. But that's more because of the age of the Signature's keycard system. Not a reflection on the host!
