Very good experience with Việt Tân Phát bus to travel between Sài Gòn and Mang Đen, the seat / bed are really comfortable and suitable for tall guys, it is worth paying a little more (compared to other bus lines) for such a long trip. I will certainly use it again later.

There is a shuttle bus to your home, few stops along the way, arriving at sg at 4:30 quite early

The sleeping area is a bit narrow but comfortable enough for the journey. The rest is too good with quality commensurate with the ticket price
