Upon arrival, there was an overwhelming smell of cleaner products, but airing the room out with the balcony door helped. Balcony access was amazing, and a little scary to look down. Sheets and furniture had old stains and spills, but still clean. Furniture is worn down a bit. Hot tub and shower was nice and strong. Kitchenette was convenient, and the fan did a great job with getting rid of food smells. Building is non-smoking, but a room near us would still smoke cigarettes on their balcony and the smell would linger into our room if our balcony door was open, but the kitchen fan did a great job with getting rid of it as well. The room only came with one pot and one pan, but I'm sure you can ask for more. Bed sinks in the middle, but it was big and mostly comfy. Valet is first come, first serve. Otherwise, you have to park at MGM Grand which is a 15 min walk from their garage to the Signature; entire walk is indoors. **Every time you self park, tell the front desk of the Signature you parked at MGM Grand and they'll give you a one-time use exit ticket or else you'll be stuck paying.
Highlights are definitely the balcony, kitchenette (bring your own seasonings), hot tub, and free parking/valet (when available). Booking through this listing is way cheaper than hotel, especially for balcony AND strip view.
