Very nice apartment with amazing garden space (very rare so close to the city center). The apartment is very quiet (despite train line nearby for those who may be concerned about this) and very well connected to Lausanne's center by public transportation (buses run every 5-10 minutes during the day and you'll get a free bus pass).
The apartment itself is an old-style Lausanne apartment with high ceilings and nice wood floors. It's not new but very well kept and clean. Since Frédérique usually lives there, it comes very well stocked and has many personal items -- so, this is definitely not a sterile AirBnB apartment!
We were also able to rent Frédérique's garage for our car for 15 CHF / day. This was very useful.
