Bonjour @Louis2786
Yes, you would have two listings on Airbnb:
- Entire place with 3 bedrooms to rent
- 2 bedrooms with you on site - category rooms in shared apartment
You would have to link the two calendars to avoid double bookings and block off dates as you already mention
If this is your main residence, then you will be limited to renting it out 120 days per year when you rent it out as an entire space. When you rent out just the two bedrooms then that restriction should not apply as long as you are able to set it up this way on Airbnb.
You'll have to obtain a SIRET number obviously if you haven't done this already and other legal matters. More information if needed on:

Good luck
