Looking for a serious shared accommodation for 3 people (brother, sister and me) – limited budget

Good morning,
We are a family of 3 (me, a student + my brother and sister) at the looking for a roommate stable and user-friendly on Paris or near suburbs.
We are all calm, responsible, and discreet. I am continuing my studies this year, and the rent will be covered by our parents and my brother, who can provide the necessary guarantees.
We are looking for a accommodation simple, clean and secure with 3 bedrooms or enough space for one flatsharing to three.
Tight budget: around €500 per person maximum, but we remain open to discussion depending on the property.
Please contact us if you have an opportunity. 🙏
