We stopped there for a night on our way back to Phoenix from Grand Canyon. It was a perfect place, that costs only $9 if you have the annual NP pass ($18 normally for a tent spot). There isn't as much space as in other campsites, but it is a very friendly place with a host Michael being super kind and helpful. Lots of different things to do around, for example we went for a short hike in the morning. Also, there's very cheap gas station nearby.
