This is the best website to book hotels and flights for very reasonable price. Go budget hotels are also very good. The best feature is that it uses go cash. There are two categories one is promotional cash and other is cash deposited by user itself.
Both of the cash categories is used. I booked a decent hotel in new delhi. It was costing 1100/day offline. With goibibo I got huge discount and it costed me 1773/- for 3 days reat of the bill was deducted from promotional go cash. I was stunned with there business model how could the afford so much! Go for goibibo.
