Sector 24C, Chandigarh: Elderly couple seeking advice on safety and amenities

Resale of our old house is almost done, and now we're seriously looking at flats in Sector 24C, Chandigarh. Kids have moved out, so don't need such a big place anymore. We want something manageable, low maintenance. My main concern is safety; raat mein kitna safe hai for elderly couples? Also, are good hospitals really close, like for actual emergency care, not just clinics? And for morning walks, is there good green cover and peaceful parks nearby? Yaar, is it a walker-friendly area overall? Any recent residents, please share your experience.
