To the contrary of general belief that builders are not so nice people, Aparna is a little different. People other than the sales people are nice as well. Like everywhere else give and take and little patience goes a long way with these guys.
Yep there will be problems, due to poor coordination between project teams (Plumbing, electrical, flooring etc. they tend to not gel well..) but they would take care of all complaints.
They replaced 20-25 tiles in my house (Seepage due to a cracked joint in bathroom fitting, some tiles had acid marks on them), without me having to push. Silicon paste, granite adhesive, grouting etc. need to be checked by the owner before hand over and they will promptly fix them.
They are very reluctant on customization. You need to push for it real hard. Layout of project is not done professionally, like it if you like it, otherwise cant help it.
