No more children at home, we have now plenty of space! One small room with a double bed, and its shower, in the house ( linen ready). Our house with the view to the lake and the Alps is in a very quiet place; close to EPFL ( 7 mn drive or a bus at 3mn walk from us), 10 mn train to Lausanne, 12 mn walk to the lake side and its beaches. Close to the Alps and Jura to hike. Other accomodations can be made ( i.e, a second room). Pleased to meet you!
Other things to note
You can book a 2nd room with a double bed. The conditions are the same than for the 1st. You find the space to book it on the same name Face to the lake and the mountains. Aibnb doesn't allow to book 2 rooms in the same time.
