Great stay at Christian's place, the flat is beautiful and very clean. Well equiped for longer stays, near by the center of lausanne and the EPFL on the metro. Despite the great heat outside the flat stayed relatively fresh. Christian is a very enjoyable presence, and is discrete the rest of the time. The only slight down side is when the weather is hot outside and you leave the window open at night there might be some noises in the morning, however the moment the double glazed window is closed its completly shuts off the noise.
Thanks a lot Christian for a great stay!
