I am very satisfied with the service policy of Phuong Anh bus company.

We booked tickets without paying for the Nha Trang-Da Nang journey (which is very convenient if you don't have a foreign card to pay with). We arrived at the bus station (the departure point was indicated on the ticket), and they printed our tickets for us at the ticket counter. We also decided to buy tickets for the return journey directly at the counter, as the price was the same in the app. We first took a minibus to the meeting point, and then transferred to the sleep bus itself. I recommend bringing a warm sweater or a thin jacket/vest, as it was occasionally chilly, and the blankets were old, but they were available. USB ports for charging your phone worked, and there was toilet paper and toilet paper. Everything was quite clean. We traveled back from Da Nang (Da Nang bus station, Terminal B2, Exit 8) on a different type of bus with three rows of reclining seats. It's less spacious, but still quite comfortable and much better than an 8-10 hour ride sitting down. We also stopped near Nha Trang and were then taken to the station by a small bus. They also transport packages during the trip, and there may be stops. I recommend this company and book VIP seats.
