I had a great stay in Lausanne, work mixed with pleasure. Close to the metro and train station, lakeside, and easy to sort out essentials: pretty much next to a little supermarket (and a larger coop a block down), a drycleaner, a wineshop, a defent pizza place and for the morning after a pharmacy. All you need in an instant. Very easy check in and check out, and Djamel keeps lots of thoughtful little extras for airnbnb guests, such as up-to date culture guides, international multiplug by the bed, nespresso machine, decent wifi, etc
Highly recommend staying here.
