We enjoyed staying in the bottom unit. It had a lot of the basics that you need and the little touches were thoughtful. Charles was a responsive and accommodating host.
One thing to note is that this is a bottom unit and there is no AC/heat. There are fans for the summer, but it was chilly. Another note is that all activities in the above unit can be heard due to the thin walls/ ceiling so bring ear plugs if you are a light sleeper. Overall a good experience.
