This was a nice stay, about a 5 minute walk from the strip with very friendly staff! Attached to the MGM Grand, which has late night food options, casino and shopping.
We experience some issues with cleanliness on arrival, vomit in the tub, and on the cabinets in the bathroom that got missed, and dirty jacuzzi jets. It was addressed after 1.5 days, not as quickly as we would have wanted, but it did get addressed free of charge. Communication through text was quick and polite. Located on the 21st floor, you get a really beautiful view with balcony.
Overall we really enjoyed our stay at the signature, would stay here again.
