Good, reliable and they are honest and upfront. Always offer good advice on restaurants too. I like their rating as it gives us a good indication of what to expect.
I booked a car rental through Zuji and there was no mention of cancellation fee, however, when I cancelled on the same day, they deducted $260 for cancellation. You only see this cancellation fee after you booked and when they confirm the booking. A ridiculous company, trying to make little money off you.
