The bed & pillow are lumpy. There was no hot water for showering. And I was kept up all night by the noise of the traffic on the interstate.

We stayed at the Diablo Mountain Inn for nine nights at the beginning of October 2025. It was our first trip to the USA and what a welcome by the fantastic Chance Taylor we had (all staff that we encountered were lovely!). She was very helpful and continuously sourced information for us. The motel is located within easy walking distance to the BART station, to restaurants and to downtown. We found the rate very reasonable. There was a good-sized fridge, a coffee maker, and a microwave (for that important tv dinner) so one does not always have to eat out. The room was cleaned regularly to a very high standard. Some people commented on traffic noise: yes, there was some but we didn’t really notice it most of the time. We definitely recommend this motel and will be staying there again on future visits.

The Inn itself is nice and the service was good. It’s just right next to a highway. The noise in the room with the windows and door shut wasn’t too bad, but outside it was pretty loud.

Hidden Gem in the East Bay I felt I found a hidden gem in the East Bay and will stay there when ever I visit again!

Easy parking and check in, friendly and informative staff, large clean room, comfortable bed, quiet nights sleep. Nothing fancy but everything you need.

Definitely worth the money. I had a family event in Lafayette so it was really close. The only downside was the traffic noise from the highway and from Mt Diablo Blvd, but not a deal breaker by any means.
