We had a wonderful stay at Yavapai Lodge. The unit we stayed in was quiet and located a short walk (via a paved path) from the main lodge, general store, and bus stop. We were able to park right in front of our unit, too. The room was clean and comfortable. It contained a mini fridge but not a microwave, which was a little disappointing. I heard there was a microwave in the main lodge but did not go looking for it.
Overall, I would definitely recommend this motel for a stay at Grand Canyon. You can't beat the proximity to all the splendor of the park.
