CGHS Mayfair: Actual construction quality vs promises?

₹2.2 crore for a 3BHK in Vasant Kunj — I'm looking at CGHS Mayfair Apartment. I work in real estate, but buying for myself is totally different. Builders ki marketing spin toh pata hai. Has anyone here actually bought a flat there? I'm worried about the construction quality, yaar. Post-possession, kya seepage issues aate hain ya plaster cracks? Also, super area vs carpet area ka game kitna hai? Not sure if the advertised numbers are real. What was your possession experience like? Any nasty surprises at handover? Off the record, what's the word-of-mouth reputation?
