We stayed February 21 on our way from Las Vegas to the Grand Canyon.
The entire property is non-smoking, and guests are asked to sign a non-smoking policy on check-in. Ashtrays are provided outdoors for guests, however.
We reserved a queen room, and it was very slightly on the small side--if you have a lot of luggage, you may feel a bit cramped. There was no closet, but a bar for hanging clothing is provided.
The room was very clean, with reasonably new furniture in good condition. A wall between the sitting area and the bed provided both privacy and sound-proofing, although it was possible to hear guests speaking in the next room at times.
There is definitely a train nearby, but I believe our room was in a part of the motel farthest away--at any rate, the train did not disrupt our sleep.
The breakfast was basic (cereal, oatmeal, bread and english muffins for toast), but coffee and juice are available in the lobby all day. The woman on staff was extremely friendly and hospitable, and the location was easy-on, easy-off for both Route 66 and Hwy 40.
For under $40, this was a good deal.
