My wife and I were at the Sahara when we first got married almost 50 years ago and it was nice then and it is still nice. Our specific room had an incredibly noisy neighbor. The hallway doors are also very noisy as they slam shut. Our room looked out to the west over the west parking structure and there happened to be a car that had the car alarm go off both nights and blast the horn for an extended time to wake us up.
This isn't really the fault of the hotel, but my original plan was to rent a house not a hotel room. I just wish the house owner hadn't canceled our reservation at the last minute resulting in a hotel stay instead.
We had no issues checking in at the front desk with our airbnb reservation (others had complained about this) and we enjoyed the free parking. Their elevators are plentiful and swift. The room was exactly as pictured including the light up mirrors on the walls. The bed was comfortable, there were plenty of towels. The hot water could be hotter.
