Eric's apartment was amazing: it was extremely well-kept, and located in a calm neighborhood that is easily accessible by public transportation. He also very kindly gave us a thorough introduction of the city, things to see, places to eat, as well as possible excursions in the region (a hike in the gorgeous village of Saint-Saphorin is a must, I would say). Definitely a big part of what made our stay in Lausanne memorable. Merci bcp!
