Recommendation for student residences in Paris? Tips for accommodation process?

I will be doing an Erasmus+ exchange for 5 months in Sciences Po Paris campus and am looking for accommodation alternatives. What are some student residence recommendations for a female exchange student? It can be both public (CROUS) and private but hopefully up to 800€ per month.

Also if you have any tips for me like residence aid/formalities in Paris regarding student accommodation, it would be appreciated!
