I enjoyed my stay here. Valet and bellhop were very friendly and courteous. Room was clean and had a great view.
This is my first time in Vegas and got lost when I entered MGM Grand instead of MGM Signature to check in, but the front desk kindly directed me to the right place. Self parking is at MGM Grand, which is a bit of a walk from the Signature, so would highly recommend using the free valet service (+tip)
