I've traveled across the country and I always stay at KOA. This is a comparatively small location compared to most, but what they lack in spaces and amenities, they make up for in quality and friendliness! This was by far the cleanest, friendliest KOA I've stayed in. I was only there one night, and I stayed in a Cabin, as I always do.
Upon arrival, I was greeted by Marvin, the location cat, and the best concierge! I was early for check in, and the office was closed so I headed into Santa Fe (a short and easy 20 minute drive away). When I came back for check in I was greeted warmly, and given a rundown of where everything was, along with a kind offer to move to a cabin that was closer to the bathrooms. I declined, just because I really liked the decor in the cabin I selected (music themed, very cute!). The facilities are very clean and ready for use and the staff makes you feel like more than just a guest. They recommended places to eat, with follow up descriptions of their favorite things to eat there, I can definitely back their recommendations of Cafe Fina and Harry's Roadhouse!
I only stayed one night, but I will definitely return next time I'm looking to stay near Santa Fe!
