If we had come to Joshua Tree to hike in the park, I think the Retro Zen Den would have been fine. I would still have wished for mattress pads on the beds for hygiene's sake, a real second bedroom instead of a converted walk-in closet, and a bar or ring for a hand towel in the bathroom. The unit is conveniently located and very clean. It is well designed and built, and the furnishings are fabulous! There are soaps, shampoos and lotions which looked like they were left by previous guests. The kitchen had adequate tableware and cookware. The granola bars were a nice welcome and the book was very helpful.
But I was in Joshua Tree for a family event. I would have really appreciated a closet pole for the one hanger present, plus a few more hangers. An iron and ironing board would have been great. Better lighting in the bathroom would have been a big help, but failing that, I could have used a mirror on a stand that I could have taken into a room with better lighting for grooming. And a full length mirror would have been wonderful! Luckily my husband was around to snap a couple of cell phone photos so I could make sure I was presentable.
I do recommend this rental, especially for hikers who don't need to dress up. If you do need to dress for an occasion, just know to bring hangers, mirrors, etc.
