I booked 5 months ago with Jet luxury Resorts a one bedroom with Strip view. When I arrive with my family (wife and 2 kids), we were amaze by that room. It was about 1000 square feet. We had a full kitchen, diswasher, We also have 2 bathrooms and a big jacuzzi. In the living room we had a sofa-bed (queen size). And the view was great. We were on the 32nd floor in Tower 3. Walking to the MGM is only 5 minutes and it's all inside, a plus in August.
I recommend renting with Jet Luxury, they have great prices, and they give you the room that you paid for.
I'm planning a trip for next May, and I will again rent with Jet Luxury at MGM Signature.More
