Hello @Philippe
As a host in France but active here on the English CC, @Emilie tagged me on this very important subject.
Here is a link that explains what norms should be in place when renting out any type of home in France:

According to the link below, plugs that are not earthed, although functional are not up to the required norms:

You mention that you've redone the bathroom and the kitchen that should have been according to the norme NF C 15–100.
Did the electrician not check out the rest of the house? It is very important that you provide a safe place for people to stay so yes, before you think about renting out your place, please have it checked by a qualified electrician.
Only yesterday, a little girl of 10 years old died because of faulty wiring in an Airbnb that she was staying at with her parents and siblings. It would seem that there were no fire alarms in place and although listed on Airbnb, the required registration number was missing as this home had not been declared to the local authorities.
There is already daily Airbnb bashing on French media so this tragic event will highlight unforgivable negligences on behalf of the owner and the fact that there are not enough controls in place.
You should also check with your insurance before starting out on renting. If you do not live on the premises, you can take out a PNO insurance (Propriétaire non Occupant)
@Mary1523 message to you is so true. Guests will turn on every light in the apartment/house even though they are not in all those rooms and then you have the guests who plug their electric cars to your mains (without asking for the most part) so that's also something you should consider.
Make sure you are up to date also on all the administrative steps you will have to take before renting. This is presumably a secondary home? The "Anti Airbnb" law (yes that's the name it's been given) will be coming into effect very shortly so look up on the net to find out how this affects you.
Good luck
