We had a great experience at this campground, the sites were fairly private and very well maintained. The bathrooms were well maintained and kept very clean. As a hammock camper, some of the sites had plenty of spots, while only 1 or 2 of the sites had no convenient places to hang hammocks.
I had no cell coverage at all with Verizon, but Mo, the owner of the campground, is very gracious about people sitting on the office porch to use their WiFi.
Overall, Grafton Notch Campground was a very pleasant experience and perfect location to access Grafton Notch State Park!
