Jiande and Zhengchao are wonderful hosts and I enjoyed my stay at their place. The location is perfect if you want to be able to walk to the city center or to the Ouchy harbor. Since this place is so central so you will get the "noise of the city" if you have your window open. But when it's closed, then all is fine. Close to supermarkets, vibrant streets, and parks (including Jardin de Lausanne)
