The Adobe Casita experience was exactly as described, and the retreat center's amenities were second to none! I enjoyed 3 days relaxing in the hot tub, sweating it out in the UV sauna, and reading by the pool in the sunshine. Rose was extremely accommodating, and was available throughout my day to answer questions and make local recommendations.
The thing to remember is that the bathroom is elsewhere on the retreat property, so if you get up throughout the night to use the bathroom, be mindful of having to trek a bit through the darkness.
The hummingbirds and bees occupying the surrounding flora kept me company on my solo retreat, and I can't wait to go back again!!
