We had to stop somewhere between San Francisco and a Death Valley camping adventure, and this place fit the bill. They were open late, and right off the freeway, as long as you figured out that coming from Bakersfield you had to head towards LA instead of Las Vegas when you got to Barstow... we didn't and it took us an additional 5 miles and 10 minutes to get there.
It was clean, sparse, with the typical loud air conditioning. Breakfast was normal pedestrian fare with no surprises.
The people at the desk were all pleasant and friendly.
