Need a PG around Parel or Dadar, where to look?

Context : this is my first time living in Mumbai, I'm gonna be joining as a resident at KEM Hospital, currently there are no vacancies in the hostel. My budget is 20k per month a little flexible if I find the right place. If anyone has any leads or can help me out with sources on where to look I'd really appreciate it! I'd also be open to renting a flat but I don't know if that's a good idea considering I'll be able to get a hostel room sometime around March.
