No bus turned up at 7.30am luckily a post office worker made a phone calls and told us to wait. About 25 minutes later across the road a Bayon VIP bus turned up and he told us to get on that. Not anything like what we'd booked but we got to Phnom Pehn!
The van departed and arrived on time. The driver drove well. My only (and biggest) grouse was that there were a couple of cockroaches on the floor/seats which was off-putting.
Good service ! And good apps to rely on
