The high points of this listing include the amazing view, the luxurious bathtub, and a walk-in shower (as a visitor from CA, the high flow, high pressure showerhead feels quite decadent!). The hosts were proactive about sending instructions and checking in w/ me on the day we arrived. I also discovered that there was a free charging station for my electric car in the self-park garage, which was a nice perk.
The downsides: Check in took over an hour. Reception had a big line w/ only two people working, and that slowed to a crawl when one of the them went on break. That's not the host's fault, but it is something to keep in mind. Also, valet parking for Tower 2 was perpetually full during our stay, which mean we had to park in the self-parking garage. It's about a 15 minute walk through the MGM Casino to go from the room to self-park -- be sure to swap the garage ticket at the front desk so your parking is free!
