How to find a decent apartment or a broker who can help me find one?

I’m moving to kochi by the end of December and was looking for flats near my office. There are limited options in Magic bricks and housing.com. Is there any apps I am missing? If any of you know a broker who can actually help me find a decent flat, please DM me the details. I’m new to Kochi and no one to help me as well.
