NS Prime View Extension: Is it really home-worthy?

Did a site visit to NS Prime View Extension yesterday. I'm in a 2BHK in Sector 121, thinking of upgrading to a 3BHK. Brochure mein toh sab sahi lagta hai, but is it genuinely good for daily living? Actually, wait, are amenities like the gym and pool properly maintained? Sometimes brochure aur reality mein bahut farak hota hai. Is the price jump worth it for actual livability?
