Faridabad flat for empty nesters, need honest opinions

Kids have moved out, toh ab itna bada ghar nahi chahiye. Goyal Luxury Floors By Rahul Mangla dekh raha hoon Faridabad mein. ₹2.65 Cr ka hai. Samajh nahi aa raha maintenance charges actually kitne aate hain monthly? Seniors ke liye neighbourhood kaisa hai, like hospital ya market kitna paas hai? Society ka vibe bhi jaanna hai, friendly hai ya isolated?
