Radhey Krishna Apartment: Amenities vs. Reality check?

Did a site visit to Radhey Krishna Apartment last week, and it looked quite good on paper. I'm currently in a 2BHK and thinking of upgrading to a 3BHK for investment, maybe for rental income later. My main concern is, how much do those brochure promises actually translate to reality after possession? Yaar, I've heard stories about promised amenities not being delivered or being totally different. Specifically, for investors, does the maintenance charge justify the actual service quality? Is it value for money? I mean, high maintenance can really eat into ROI, right? Kya tenant attract honge if facilities are just for show? Any real-world experiences on this, especially for Radhey Krishna Apartment? Should I be worried about long-term upkeep expenses affecting my investment plan?
