Booked Savaari for Delhi Airport pickup on 28th Aug 2014 and again for Delhi Airport drop on 1st September 2014(to and from Dilshad Garden, around 30km). Pretty easy to book online. Got a good deal both times(Rs 399 each). Drivers reached on time, cars well-maintained Toyota Etios(both times).
Drivers were courteous and helpful. Will use them again and recommend them highly based on my consecutive good experience with them.
