This is the adjacent property to the first home I ever owned, which has another casita behind it that we use as a vacation rental. So if this one isn't open, inquire about one of our other homes. We surely have one that will fit your needs !! Here's a link to all of them.

With that said, We absolutely LOVE the neighborhood. You can't get any more centrally located to EVERYTHING to do in Tucson ! Close to U OF A, hiking golf, great restaurants, parks, botanical gardens, malls, downtown entertainment etc, while located in a well established quiet neighborhood that was built out in 1940's.
