for those who are considering renting motorbikes in vientaine, please avoid renting from mimi guesthouse. their bikes are in poor condition.
the first bike that i tried, the brakes aren't working(that's really dangerous). the second bike won't start, the 3rd bike seems ok until 10 mins later it decided to stop working. i had to push the bike all the way back to the guesthouse, they refused to refund my money and insist that i have to pay for repairs.
apparently the same happened to this other dude who saw me arguing with them.
