This review is for a unit on the 23rd Floor of Tower 1. The place was spotless and fresh upon arrival. Unit description was right on, with a breathtaking view, all amenities as pictured, and the most comfortable mattress I've ever slept on (It was a Serta Sertapedic, which I think I will be buying). The Signature complex is attached to the MGM Grand by an indoor walkway. But the complex also had it's own lounge, Fitness Center, and deli. If you leave the complex and take a left out of it, you hit Planet Hollywood and all it's bars, shops, and restaurants (including a flossy Walgreens that even sells liquor). It's a sidewalk walk and very safe. If you go through the MGM Grand, that has its own amazing selection of restaurants, shops, bars, and theaters. You can also pick up the monorail there as well as cross over directly to the Tropicana, which puts you right in the midst of several of the strip hotels. The only thing which I didn't care for was that the MGM Pool played loud house music a lot in their outdoor theater, but I preferred the quieter Tower 1 pool anyhow. Mark was a great host and answered all of my questions. I hope to return again to rent his unit. Thanks Mark!
