Convenient facility, with kitchen and laundry in the unit.. Off the strip, so it's a bit more quiet and and less crowded. No gambling on site.
For Marriott fans, and vacation club owners, it's convenient to have a facility in Las Vegas. They are building an additional tower
The on-site shop is open 24/7. Garage on site too.
Nice to have one, two, or three bedroom units. Beware that some folks may do bachelor/bachelorette parties, and make it tough on the neighbors. On site management is pretty responsive though.
