The French Qtr RV Resort is just a couple blocks; walking distance from the Qtr, so if you want to be right there and have great access, then it might be for you. St Louis No. 2 is literally right next door. That is where the Voodoo Princess Marie Catherine Laveau is buried. The campground is about 2-3 miles from the WWII museum.
On the less positive side, you can actually look down into it from the I-10 freeway so I imagine it's not too quiet. It's also a bit pricey. The standard rate is $105 per night, weekly rate is $680, these rates go up during special events. It's basically a flat paved area with slots for RVs. There is also not much in the way of trees, vegetation or separation from your neighbor.
