Joan is very friendly and helpful. She seeks to accommodate guests in whatever way she can. My room was quiet and had a private bathroom and shower. I was able to arrive quite late my first night, around 2am, and was left clear instructions on how to get in. Everything was clean and charming. Thanks Joan!
