Daily living in Noida societies: The real picture?

Been looking for 8 months now and it's getting exhausting. Kids have moved out, so don't need such a big place anymore, just something manageable near a good hospital. Planning to sell our big house, you know. Thinking of Jaypee Krescent Homes, but not sure about the day-to-day reality there. Logon ka kya experience hai with elevator quality aur maintenance response time? Old parents ke liye bahut zaroori hai, you know, lift ka issue. Also, power backup ka kya scene hai? Full flat milta hai ya bas common areas? Aur water supply ka kya hai, tanker pe depend karna padta hai kya, especially in summers? Resale property le raha hoon, toh ye sab baatein bahut important hain. Koi bata sakta hai actual reality kya hai?
