My husband, myself and our 6 year old son booked Sankaran for a day tour of Mahabalipuram.  He was extremely knowledge and very eager to share information.  His English is excellent and he studied in the UK.  He is also a stone carver by trade.  We appreciated his flexibility in changing pace to accomodate our very active son who has much less patience than us for learning about history.  We asked to eat some traditional food in the area and we had delicious Thali lunch together.  We'd definitely use his services when we return to the area again!
