What Satya Villa owners aren't telling you about costs

Honestly, I'm starting to think we're all being sold a dream with these 'premium' projects. I'm currently in a 2BHK in Sector 137, thinking of upgrading to a 3BHK, maybe even a villa, around Noida Extension. Everyone glorifies Satya Villa for its location, but nobody talks about the hidden charges that pop up post-booking. My friend got a 3BHK there and the final cost with all PLCs and maintenance deposits was way higher than quoted. And the construction quality? He's already seeing minor cracks. Is this premium justified? Change my mind.
