The apartment is really well located (in walking distance to EPFL, some restaurants and grocery stores). Aimé is also a friendly host.
But do clarify with him at what days of your stay you will have the apartment fully to yourself. Because the room was advertised as private when I booked it, but Aimé spent the first night of my stay on the couch, which is in the same room as the bed. I did not appreciate this, especially since Aimé continued watching TV at night while I wanted to sleep.
However other than my first night I was really satisfied with my stay.
