We really enjoyed our stay with Nat! Communication was almost instant, and all instructions were thorough and easy to follow.
There was some confusion in the other reviews about whether this was a hotel or a private residence, so let me clear that up: this property is for a privately-owned condo in one of the 3 MGM Signature condo buildings, which share the grounds of the MGM casino/hotel. Thus, it does look hotel-like and you do have access to the entire MGM casino and the several MGM swimming pools via a ~15-minute INDOOR walk as this property is in Tower 3. Additionally, Tower 3 is about a 5-10 minute walk down East Harmon Ave to the Strip, which intersects the Strip just south of Paris and the Bellagio.
As other comments said, the messages you receive when you communicate back and forth do seem canned, but they are tailored to answer all your questions and they are thorough, so no complaints from me on that.
