Karat-S receives positive feedback for its punctual and comfortable journeys, with users appreciating the friendly and helpful drivers. The functioning onboard facilities like toilets are also noted positively. However, some travelers mention a language barrier as a minor issue and express that the Wi-Fi data limit could be improved for better connectivity during trips.

Though I missed my booked trip and had to purchase another ticket, I found the trip is always comfortable and reliable.

Full bus. Seat rows close together, impossible to stretch legs. Short, 2 hour, trip; able to tolerate inability to move legs. I would NOT recommend Karat-S for any trips longer than 2 hours.

I missed the bus due to late arrival of my aircraft and they didn’t help me with the new ticket. I had to buy a new full fare ticket !

Even though we bought a ticket for a bus equipped with toilet, AC outlets and A/C, it was a bus from the nineties without anything I mentioned. In addition it was should be a direct bus but it stopped in many places every almost two hours. Very disappointing, especially we paid a very high price (for nothing).
