Now we stayed about decent hotels time to time on our travels and the cost varied as well. We stayed at a decent hotel (probably 2-3star - not even) in mumbai and that cost us 2000INR a night; in goa we paid about 1200INR a night for even a crappier room but it had AC. But on average a hotel room cost about 1000INR/night. If we stayed at a high-end we would pay 5000+INR a night.
