I did not like much about it. I had to stay there on my way to the Sierras; had a late start. The room had: TV, refrigerator, coffee-maker, and micro in the room. Bathroom was in a poor state. Stains in the toilet bowl, paint pealing off the wall. No walking distance to dining, ugly. There aren't many choices to stay in Adelanto so forget it.
