Noida Extension is only good on paper, prove me wrong

Been thinking of downsizing since the kids have moved out. Sector 156, Noida Extension dikha rahe hain agents. Looks good on brochures, but is it really? I'm concerned about water and electricity, matlab power cuts kitne hote hain? And hospitals dur hain kya? Resale of my current property is riding on this, so soch samajh ke invest karna hai. Koi rehta hai vahaan, share your experience? Maintenance costs bhi batao.
