I’ll also recommend getting a shared apartment in Andheri East.
Road connectivity between east and west is terrible because Andheri bridge is under construction for a while now.
JB nagar and Sher-e-Punjab will have cheap accommodation.
Electricity will be cheaper. I pay <2000 (Adani) total per month for a 2bhk and I work from home (display, laptop, ac, fan).
Also consider cost of maid/cook. For 2bhk it’ll be about 3-4k and cool salary will be based on number of people and meals.
Airtel Broadband has 200 mbps plan for ₹1200. Divide that between occupants. Jio has similar plans.
I’ll suggest not staying in a pg. It’s usually not a good experience; there will be curfew hours and most ‘aunties’ who run these are very intrusive. Sharing based on past experiences.
All the best 👍🏽
