He is a nice person even we barely talk since my itinerary started early every day and went back very late. On the first day of arrival, he tried to explain everything for this house on our questions with cheerful response. He gives us space even we have to share the bathroom and kitchen. For the location, it is convenient even not in a central downtown. The bus stop is only 2 mins away from the house( taking you directly to Lausanne gare, the main train station). About the metro, you can walk to the nearest in just around 5-10 mins.
