Camped here for three nights over Fourth of July holiday (site 52).  Because of the holiday and the proximity to Oakland/San Fran, the campground was in FULL EFFECT with a gang of variant families camp site hopping.   Unfortunately, the site across from mine was the epicenter of all things July 4th and the aforementioned multivariate families.  Had I chosen the site to my left, or a few more down the road, I would have barely noticed them at all - sites 47-44 had no one across the way, more private, set back.  Aside from the crew across the way playing the LOUDEST game of cornhole/bags I have ever heard (think gunshot every time a bag struck the board), the group(s) were mostly awkward lively teenagers and their parents (think Riverdale without the murders).  To the teenagers' credit, I didn't hear a curse word from the group, just pure spaz.  I think they really did create some rad summer memories.  Having said all that, if I returned I would snag site 44.  Just trust me on this.  Most of the sites are pretty decent, but 44 was the best. 
In terms of cell service, I had pretty good range, was able to listen to the Cubs win one of four games against the Pirates (the series started with a brutal take down of the Cubs 18 to 5 - don't worry - Cubs managed a 3 game sweep of them a week later).
Bathrooms are decent, not the cleanest, but well stocked and had hand soap.   Coin operated showers were also a treat (again, not the cleanest, but...).  Potable water close to sites.  Raccoons, Chipmunks and Blue Jays were NOT SHY but also not a harrowing issue.   
The win on this campground is how close it is to Point Reyes National Seashore, San Rafael, Olema, Novato and Marshall.  I would highly recommend Five Brooks Ranch in Olema for horseback riding, Hog Island in Marshall (snag a picnic table and shuck your own oysters - definitely a highlight) and Cowgirl Creamery in Point Reyes Station.  Oh, Point Reyes Yoga - yes to this!  - also in Point Reyes Station.  Novato had the most adorable 4th of July parade complete with a pancake breakfast.  And San Rafael - home of Terrapin Crossroads - music venue of the one and only Phil Lesh was also a highlight.  There is also Kayaking in Tomales Bay which is okay fun.
Overall, this is a campground that checks a LOT of boxes.
One thing to note, the night is COLD up this way, and mere miles will cover several different weather systems.  Bring layers.  
Happy camping!
