We availed the cab services for 8 days (Sunday pickup at Ahmedabad airport to next Sunday drop at Udaipur airport). In between, we travelled through Mount Abu, Kumbhalgarh, Ranakpur, Chittorgarh and Udaipur City.
It was a great experience for us. The car we took (Innova Crysta) was new and in great condition. Our driver (Bhavani Singh) was also excellent. Very safe and careful driving, always punctual, knowledgeable about good restaurants on the way.
Charges were reasonable.
Would definitely recommend to others planning to do a similar Udaipur based trip.
