The apartment was close to the M1 metro station "Malley" (~5 minute ride to University of Lausanne stops or ~ 8minute ride to Lausanne-Flon in the heart of the city) and the train station "Prilly-Malley" (~3 minute ride to Lausanne main station ("Lausanne-Gare")). Supermarket "coop" right there, too.
The apartment was nice and since I kept the windows closed, I didn't think it was loud at all! Would stay here again.
