Nice campground right in the middle of town. The noise was no worse for us than anywhere else that we've stayed, better than many. There are plenty of restaurants, bars, and tiendas, within close walking distance. The pyramids are not a bad walk, and really impressive! We couldn't get wifi to work here, but another couple had luck sitting right next to the office. Her dogs didn't bark at all while we were here. We paid 200 pesos per night.
