A nice hotel option, upscale, architecturally a bit severe but with a very nice view of the mountains (not so much the lake). Overall, the neighborhood is very safe but unattractive: EPFL is not a campus notable for its grade, and the hotel has some sort of muddy field behind it (but with a path you can follow to walk on the side of the lake, which I recommend). Restaurant is good but has a limited choice; bar is fine but mostly has fairly cheap liqueur at relatively steep pricing. But the staff is incredibly warm and helpful, and we valued that.
If you plan to use the sofa or sleep on it, ask for a room with a sofa that isn’t ancient and lumpy. Only some rooms even have a sofa, but among those that do, many should have been replaced around 1975!
