I have had several occasions to visit prestige constructions site and found that the open space provided is too large and have very good amenities compared to sobha or brigade(of their levels). the quality of construction is also been at good levels.without doubt it is best in bangalore.
Prestige shantiniketan in whitefield is the best example. However, the rentals compared to other equally good builders is less by 2000-3000 for a 3BHK as a result, people have doubts on its quality. But nothing to fear, it is the locations also which matter.
