Ansal Aastha: Real carpet area and hidden costs?

I've seen this pattern before, but Ansal Aastha Mig Zone's carpet area claims are making me rethink. For a 2BHK on Kalawad Road, super area felt inflated. What's the real carpet area people got? What were post-possession maintenance charges? I'm calculating true cost, not just the 70-80L price. Any surprises during handover?
