I brought my sister to Desert Hot Springs for her birthday (we're both seniors), and we really enjoyed staying at the Desert Vortex Retreat. We only used two of the three bedrooms, but all had ample space at the end of the bed to do stretching in the mornings.
The kitchen was well-equipped, as were the bathrooms, and the sofa was very comfortable. We couldn't sit outside because it was super windy, as it can be in the desert, but we enjoyed excursions to The Palm Springs Aerial Tramway for hiking up at 8,500 feet, and Miracle Springs Resort right there in town for soaking in several of their 8 naturally heated pools.
The neighborhood is quiet, and there are beautiful sunsets. I would stay here again, and highly recommend it!
