Originally a VIP destination, this charming property features four rooms, early 1900's dining room, and captivating historical photos. With recent investments in new electrical and plumbing, it offers a solid foundation for restoration.

Positioned in the heart of Ajo, AZ, this property blends history with opportunity. The garden, outdoor seating areas, and serene retreat with scenic views offer a peaceful escape. Just a short walk to the downtown plaza and a leisurely stroll through the historic district, this property is beloved for its charm.
