Carpet area claims are mostly marketing fluff, Maitri Apartments included?

Maitri Apartments ka carpet area actual mein kitna efficient hai for daily living? I'm currently in a 2BHK in Dwarka and thinking of upgrading to a 3BHK. Site visit pe floor plan dekha, laga spacious hai, but I'm worried about usable space once furniture and sab kuch aa jaye. Kya walls too thick hain ya odd layouts hain? Noise levels aur daily life quality kaisi hai wahan? Is the price jump for a 3BHK justified if the carpet area isn't truly practical? Ya sirf numbers pe achha lagta hai?
