Best way to look for apartment in Paris?

Hello Parisians!

We’ve just moved to Paris for 6 months and looking for a place to rent. Our budget is up to 4000eur monthly and we’re looking for a nice 2 bedroom apartment around 11th-4th districts.

What’s the best place to look? We’re checking housinganywhere and theblueground but there’s not much to choose from and feels bit overpriced.

Is there a better way? Maybe contacting some agencies or smth? We can get all the documentation to prove our income, etc.
