The service attitude was excellent. As soon as I booked the ticket, the staff called to confirm, I changed the route and got 10,000 back right at the station. The best thing was the driver picked me up from Tan Son Nhat airport to 508 Kinh Duong Vuong to get on the bus, it was pouring rain in Saigon but he still picked me up on time, drove very carefully. When I arrived at the station, I forgot to tip the shuttle driver. Very wonderful. Thank you Hue Nghia bus company.

The first highlight is that the car is clean, the pillows and blankets... everything is fine. The pick-up point is not the same as on the app, so guests have to move to the bus station themselves. The transfer vehicle is a 7-seat car. The transfer driver is polite and knows the way so he takes him to the gathering point on National Highway 1A quite on time. In general, quite satisfied with the garage.
