I stayed with Yan after a long journey into Lausanne. She was accommodating, incredibly helpful, she had the sofa bed pulled into a bed and had cleared out the closet in the front hall for me to use. She responded to my questions about the neighborhood (even after having arrived) within five minutes (not kidding!) and was so kind and considerate of me and the space that I may have needed. She would give me space if needed, but also was ready to engage in conversation when I came home after a long day of classes and interact with me to help me understand the way things work here. Highly, highly recommended :)
