Compared to nearby areas like Saibaba Colony and R S Puram, Vadavalli offers the calmest atmosphere. If you can shell out 15000 per month, you will get solid multistorey apartments. Hope that helps :)
Hey! I recently took up a house in IOB colony. Vadavalli has a really vast range of rental prices from 5000 to 15000 per month. Because the place is in one of the greener sides of Coimbatore, expect wonderful weather
