Builder never address the problem permanently, I don’t know how they got good review, do not look outer structure, inside it’s too bad because each and every day we are facing noise, bad smell and they are not able to address these common issues. Apartment is having issue with the STP, water, gas smell, bad smell, noise sound etc. donor go for it, put some extra money but buy from trusted builder.
Without communication they will put some rubbis stp and they will say it is architecture plan, I don’t know who is this architect who design in such a way so that outer part look good but internally people will face health issue related stuff daily. For family who is having kids this is a warning don’t go for it otherwise something worst is waiting for you.
