We took a day time sleeper bus with HM Happycar from Hoi An to Phong Nha. I received a WhatsApp message from the organizer to ensure we found the bus ok before departing. The bus was extremely clean and in great condition. The little bed capsules were private and lay totally flat, or you could put them into a partially reclined position. I am 5'4" and could lay completely stretched out, my friend is 5'9" and could do the same with flexed feet. There was a USB port, lights and air vents. The driving felt very safe and there were two drivers who traded off which helped us feel safe as well. We stopped 3 times for toilet breaks. After getting dropped off and going about our day, we realized we forgot air buds on the bus. I messaged them via WhatsApp and they responded immediately that they would ask their cleaning staff. They found them and organised a nearby hostel for them to be dropped off at for us to pick up at our convenience. Very impressed overall, would book with them again.

⭐ 4.5/5 Thanks to the Vexere app, I had a pretty good trip with HK Buslines. The bus was luxurious with a private cabin for each passenger, and the staff were friendly and attentive. Vexere’s hotline worked efficiently and showed responsibility toward customers. Cons: -0.5 star because the booking process on the app is too quick, making it easy to select the wrong step and impossible to go back, which could result in service cancellation. -0.5 star because drop-off is only at the company’s representative office, not at my home :) Pros: The bus departed and arrived on time. Pick-up was exactly at the registered location. Professional and helpful staff. Overall, I rate 4.5 stars for both the Vexere app and HK Buslines. I hope the app and the company will continue to improve to provide even more convenience for passengers. Best (Nhờ có app Vexere mà mình được trải nghiệm chuyến đi bằng ô tô của HK Buslines khá ổn. Xe sang trọng, mỗi người một cabin riêng, nhân viên phục vụ nhiệt tình. Hotline của Vexere làm việc hiệu quả, có trách nhiệm với khách hàng. Điểm trừ: -0.5 sao vì thời gian thao tác trên app quá nhanh, dễ chọn nhầm bước và không thể quay lại chỉnh, dẫn tới nguy cơ bị hủy dịch vụ. -0.5 sao vì khi trả khách, hãng chỉ trả tại văn phòng đại diện chứ không trả tại nhà riêng. Điểm cộng: Xe xuất bến và đến nơi đúng giờ. Đón khách tại đúng địa điểm đã đăng ký. Nhân viên chuyên nghiệp, nhiệt tình. Tổng thể, mình đánh giá 4.5 sao cho cả app Vexere và HK Busline. Hy vọng app và hãng sẽ ngày càng phát triển để mang lại trải nghiệm thuận tiện hơn nữa cho hành khách. Trân trọng)

The first time I went from Nghe An to Da Nang, I was a bit worried that the bus company was cheating me, but in reality it was very ok. The bus company was friendly, the operator called to confirm and remind me of the schedule to avoid missing the bus. 10 minutes before the bus arrived, both the driver and the operator called. All information about the license plate and the driver's phone number matched the email received. I kept the seat I booked for myself. The bed was spacious and comfortable, the bus ran smoothly and had no smell, and I arrived in Da Nang almost 1 hour earlier than the scheduled time. 10 points, next time I need to choose this bus company to go from Vinh <-> Da Nang

We should really support good bus companies like Khanh Quynh, from the attitude of the drivers, staff to the facilities of the bus. The buses are new and very clean. I just hope that Vietnamese passengers will travel in a more civilized manner.

Good service - the assistant driver is cheerful and cheerful - the bus company needs to maintain trust - thank you for the experience of the trip!
