Guilhem's place is conveniently located to downtown Lausanne. I recommend taking the metro line #2 to CHUV because it's easier than the bus. The bus stop is closer to the apartment, but if you arrive by train it's an uphill climb on cobblestones to get to the pick up stop in Lausanne (which is okay, but a bit of a haul with luggage!). The apartment is very comfortable, modern, and well-furnished. Although I did not meet Guilhem in person because he was traveling, he made it very easy for me to get the key and was readily available if I needed anything or had any questions.
