I have been using Uber app and its services since an year. It is a very good taxi service. There is always a driver available near my place so the cab always arrives in about 5 minutes. I book Uber cabs even for my Grandparents whenever they need to go somewhere.
Uber drivers are very good drivers, helpful and generous people. They are always happy to help others, and always explain the travel expenses if someone has problem with it. Once my grandfather had too much luggage with him so the driver of Uber, helped my grandfather with the luggage.
Uber cabs are always clean and comfortable. The cost of travel is also moderate so I am always happy to book Uber for short as well as long travels.
