Sector 99 Noida: Investment sahi hai ya galat?

Thinking of investing in Sector 99, Noida. Property prices seem high. Do they justify the location? Has anyone seen good appreciation here recently? Also, what's the water situation actually like? Heard mixed reviews about water supply. Anyone facing issues? I'm worried about resale value later. Is it easy to sell here if needed, or will it be a loss? Mujhe advice chahiye yaar!
