I travelled from Brahmavar to bangalore airport with Sugama ac sleeper. I have rated the service was good and the website is excellent.
I have not given 5 star to the bus , because it is not as comfortable and smooth as volvo and the bumps and twists are going to cause motion sickness to those who are prone .There is also no provision for any disposable bag in case u r nauseating.
The bus came a little late (that we can adjust) but the driver was very swift and took off in a jiff and was fast through-out.. kudos to him, as he took us safely through treacherous ghat roads and reached our destination, but a little late (One hour late than mentioned on website).
one thing with the private buses is that they stop in weird places..
but still I feel it was safe for a lone night traveller.
Finally, If u are planning to go to Bangalore and that too starting from a small place, u have to choose this service as there is no other better alternative.
KSRTC volvo doesnt provide services in such places
