Camping in Yosemite is a matter of tradeoffs. You can be near the Valley and in the middle of crowds, way up in the wild with few facilities or in the middle and that's Crane Flat. You'll be just down the street from one of three gas stations in the park and an attached store [hours are 9-5 daily] which is great since you'll be driving 25 minutes to the Valley, 35 to Tuolomne Meadow, 50 to Glacier Point, or 60 to Wawona.
There's 4 or 5 loops each with several dozen camp grounds so not overly crowded although it does fill up and sites can be close together. Noise becomes an issue based on the neighbors... we had some who were too loud but for the most part the place was near silent. Save the sound of campfires of course.
In terms of facilities again it's somewhere in the middle of options as far as campgrounds go... You get restrooms with real sinks, potable water but no lights, showers or dining. For those you have to head down to Curry Village / the valley.
And remember, you're in Yosemite. The goal is to get out and enjoy... not sit at your camp site all day.
Look at the map closely before you pick a site and try for corners and sites that may have more room...
