I am a hostelite student, so I used cabs many times. I use both cabs ola and uber.
UBER has comparatively cheap rate. Also they have some good features in their app, like pick up of food from on the way hostels etc. But the problem is the drivers of cab. They are not that professional, they neeed to train more
Sometime they misbehaved with customer. Cabs are good, travel convience is also good. If they could train their drivers it would be best.
