Excellent. The tour operator has shuttle buses to many locations, a clean private waiting room, free snacks, fruit juices, and wifi. The driver is polite and courteous. The only small minus point is that the restroom is not clean and convenient (lack of toilet paper and hand washing lids).

I traveled with my wife from Saigon to Danang. Everything was fine. The bus was new and comfortable. The staff didn't speak English, so we had to use Google Translate. They showed us where toilets were and where to eat. The bus stopped 4 times within our 16-hour trip. We arrived 3 hours earlier than expected. Authentic experience :). The main problem was the company changed our pick up point. They were calling us a whole morning to inform about it but we couldn't understand Vietnamese. The manager in our hotel helped us.
