Is Kasturi The Balmoral Hillside worth the premium?

Honestly, I'm finding this home search way more stressful than I thought it'd be. Currently in a 2BHK in Baner, I'm thinking of upgrading to a 3BHK or villa and Kasturi The Balmoral Hillside caught my eye, but the price range (₹4.46 Cr–₹11.20 Cr) is a huge jump. Is it genuinely good for daily living or just looks fancy on brochures? I already have a home loan, so the premium needs to be justified. How's the actual carpet area efficiency? Do the layouts feel truly spacious for a 3BHK, or is it just the built-up area making it seem big? Also, what about noise levels and air quality there? Is it a peaceful home or too close to any busy spots? Really appreciate any owner experiences.
