The bus company's service process is very good, with very few areas needing improvement. However, it would be better if the company changed its tissue paper supplier, as the tissues have a slightly strange smell. Otherwise, I've witnessed many changes in the bus company over the past two months: drivers and bus assistants are increasingly friendly, the service process is clear and efficient, and they've resolved the transfer bottleneck in Hanoi by assigning specific zones to each bus.

Sleeper buses offer a comfortable and convenient travel experience, especially suitable for long journeys. The spacious and comfortable sleeping berths allow passengers to rest and reduce fatigue compared to regular seated buses. The air conditioning system operates smoothly, and the bus runs quietly with minimal vibration. The buses are equipped with amenities such as blankets, pillows, privacy curtains, phone charging ports, and Wi-Fi, creating a pleasant feeling throughout the journey. The drivers and bus attendants are enthusiastic, courteous, and drive carefully, ensuring passenger safety. Buses depart on time and make convenient stops for meals and restroom breaks. With reasonable fares and good service quality, sleeper buses are a reliable choice for long journeys, especially nighttime trips.
