Sector 21 Noida: Metro and real life, sahi hai?

Guys, I'm thinking of buying in Sector 21, Noida. How's the metro connectivity *really*? Like, morning rush mein kitna time lagta hai to reach office? And is it peaceful living? My parents keep saying it's too crowded. Also, kya aap logon ko pata hai about water supply? Sunne mein aaya hai tanker vagarah pe depend karna padta hai. Investment wise, is it worth it? Mujhe advice chahiye yaar.
