It was clean. Pared down. I asked for extra pillows, and received two. Very helpful receptionist. The heater was interesting and didn't work well. The receptionist helped me figure it out. The tub in the bathroom had no stopper, or it was broken. No bath for me. No breakfast, no coffee.
Homeless people sleep along the road leading to the hotel. Car alarms went off 3 times, and the new receptionist said they didn't hear them (!). I asked that they please listen for them. The alarms stopped.
There is another Motel 6 in Vallejo, called Napa Valley. It is moderately better overall, has complimentary coffee, breakfast, other amenities. Do your homework, it might suit you better. In the rnd, this was a place to sleep, but I didn't sleep well.
