I don't know how familiar you are with the 206 jacking set-up......
There are four reinforced areas on the sill flanges, if you look closely they are marked by two cut-outs, this is where you're supposed to lift the car with the "crappy" jack supplied ( I always carry a trolley jack in the boot).
As you can just about see in the photos, I've got my jacking points marked with white paint, to make it easier to find them in the dark, if I need to change a wheel.
If you don't like Benny's "brick" idea, which works okay for me, you could jack up the front offside of the car, using the sill point, then drain the oil and lower the car again so that it's level and let remaining oil drip out.
As I'm not exposing my entire body under the car, only reaching for the plug, I don't use axle stands ( can almost hear a growl from Health and Safety Gestapo!) but this was the way we used to work in garages in the good old days, as the foreman always advised " time is money, Benny, get a move on!!"
