Excellent, comfortable bus journey - works definitely recommend. Contact from bus conductor was perfect, and when he came to meet me personally at the pickup spot he had my details which was reassuring. He also gave plenty of advance warning of the final stop in Sa Pa so passengers could be ready to depart, and was clear about how long we had at rest stops - he really was great. I have only 2 criticisms - and as far as I understand, they was not the fault of the bus company or conductor, rather because of the ticket I booked through Vexere - the pickup time I was given was 45 minutes before official departure (as is normal), but we actually passed by the exact same place and picked up more passengers around an hour later, having gone all the way around Ha Giang! It wasn't a big deal and I was comfortable (and I knew we'd be collecting more people after me because of my pickup time, just not that we'd be going part my exact stop again).. but who really wants an extra hour sitting on a bus for no reason? Also, when booking my seat the configuration on the app was incorrect so although the seat number I hadwas correct, it was not in the place I expected (opposite side of the bus, and a top bunk instead of bottom!) - it could have been user error on my part but if so it wasn't clear on the site, so be super-careful when selecting seats! Again, not the bus company's fault at all - everything about my journey was perfect.

The informations about pick up locations etc are a little approximative, I asked Vexere where we could get to the big bus directly and at the end the location was still a mini van pick up that brought us to the bus but that is not a big deal. We left on time from Hanoi but made a very long break at the airport to wait some passengers I guess and arrived only 30 minutes late in Sa Pa so very good. There is no WC in the bus so think about it but you’ll do two 30min breaks in freeway area (3k dong to use the bathroom and they are very clean) and will also be able to buy a lot of different snacks and food. Very confortable seats ! Keep in mind that sometimes the quality of the roads is not that good so it can be very shaky. We booked the top 2 seats at the very back of the bus and you can feel the bus vibrating a lot, the lower seats just before these seats were much more confortable and we were able to use them as they were empty. Overall a very good journey :)
