I need help in finding a place near BKC

Hey everyone, I'm (23M) and I just got a job at Google Mumbai, and being somebody from Pune, I'm finding it confusing on how to rent out something there ! I'll be joining in on 1st week of April The pay is less according to Mumbai standards, but I'm willing to pay 15k for a room. Please don't call me very demanding, but being from Pune I have been used to extra space and good looking societies, so when I started looking for places in Mumbai, I found such societies charging 1 lac for 3 bhks and 40k for 1 bhk, how do I find a nice place which is close to work (BKC). I just want a decent place with a well functioning elevator and sorry for being too demanding at least a balcony🥲. Not sure how I can find people as room mates, it's gonna be a costly affair. I understand why Mumbai is so costly and hence I wanted your expertise in helping me find a steal deal in Mumbai in a good locatilty or society. And please also tell me which place would be the best from BKC, as my mode of transport to office would be cab. I feel the best thing is to find a 3 BHK for 50k and split it among 3 people, please guide.
