As you might imagine for an old Route 66 joint, it has a Wikipedia page.

It was built in 1939 by Charles G. Wallace, a local trader of Zuni art and pottery, who remained the owner until 1983. Wallace decorated the motel with a variety of Native American art, including a series of murals by Zuni artist Tony Edaakie in a basement room. Commissioned in 1951, these murals are one of the De Anza's most notable features. The motel was purchased by the city of Albuquerque in 2003.

Rescue and renovation seems to be underway, but who knows how these things turn out.
