Newbie here,Which areas to look for 1bhk flat max budget 15-16 k

I got a offer from company in Belapur diwale Goan,My max budget is 15-16k for unfurnished flat . I rented a lodge for 20 days near dy patil and asked locals for suggestion ,here is what they said Nerul- lot of garages ,sound bahot ayenga Area is good. Kopar khairane- Residents for all ladies bar girl and escort choose area carefully. Belapur- Everything is good but out of budget 20 k is starting it seems. Vashi -Expensive Taloja -Little far Kharghar - It is good but ,but industrial area is there which causes pollution. Please redditors as newbie can you help me out or provide specific sectors to look in for my budget . My requirement are Gym should be nearby and uber Auto cab accessibility is must. As it is night shift ola,uber should reach anytime for pick up . My mom would be staying with me so groceries and kirana store should be at walking distance. I may be wrong in some aspects it's just 5 days I have been staying in Navi mumbai. As I started asking more they were inducing me to hire a broker. I don't mind hiring a broker but as I have already booked a lodge for myself,I might house hunt in evening and keep it as last resort . Sorry for long post. Thankyou for your suggestions.
