The good news was that Tom the property manager was extremely easy to communicate with. He was quick to reply to questions and accommodated our request for an early check-in. He also quickly agreed to a full refund after we listed our complaints and told him we wouldn't be staying there. Dealing with him, considering the issues we had, was refreshingly pleasant.
The property itself was filthy. It is clearly lived in by someone when it is not being let. Whilst there had obviously been cleaning activity prior to our arrival, the focus had been on the beds, floors and kitchen surfaces. The rest of the place was covered in dust, which Tom told us was due to construction nearby and high winds. 
Much of the kitchen equipment was in need of replacement. The oven looked like it had never been run through a cleaning cycle, the toaster needed to be thrown away, the Kurig coffee machine needed sanitizing and every shelf and cupboard was brimming with old, worn kitchenware. The pots and pans were old and tossed haphazardly into their cupboard. None would I have wanted to use. The dishwasher food-trap was full, the fridge was old and worn, although there were two eggs thoughtfully left for us. No idea how old they were. 
Despite being assured that the property was absolutely pet free there was a half-used bag of dog food in a kitchen cupboard. 
The cupboard/pantry was full of a wide variety of foodstuffs, mostly used and looking the worse for wear. There were numerous empty containers that just needed throwing away.
The rug in the living room was stained, and the sofas were both in need of either replacement or steam cleaning. 
There were numerous light bulbs not working throughout the property.
The bathrooms were clean, but tired and worn. 
Our reaction to the property was one of extreme disappointment. We travelled all day from the east coast to spend 4 days in Santa Fe. We took photos of all these issues and showed friends and family. They were very suprised at the state of the place. We thought we had found a gem, but this place needs a very deep clean and a lot of items replaced. I cannot recommend this place while it remains in it's current state.
