For one night as long as it exists when you get there, has parking, and is acceptably clean, it'll be fine.
When we drove to northern Spain in the days before budget airlines we stayed in this unstaffed, automated motel place, that made Travelodges look like The Ritz, on a service area that had several of these places somewhere in the middle of France. But it was a cheap bed for the night, which was all we needed.
These days with the internet and all that, I tend to default to Booking.com, for which I wasn't sure why, but after reading @Caroparo52 post, it makes sense, it's a good search facility with sensible filters that I like.
I also like to know exactly where the property is, which is the main thing that puts me off Airbnb, because we like to be in walking distance of restaurants and other amenities.
But I found hotel booking a lot easier when I realised I didn't need to compare and contrast a huge shortlist to find the best hotel, I just needed a nice one for the right price in the right place and once I've set the filters right on booking.com, I usually end up booking one of the first two/three I click on.
