It's really easy to use, convenient, less expensive than local taxis, and safe.

Just be careful - the drivers are pretty unethical. More than half of our drivers didn't turn the meter off when the ride ended so we were slightly overcharged. $1 here and there isn't a big deal, except when our driver who took us to the airport drove all the way back to the city without turning the meter off costing us more than double our ride. After reaching out to Uber, they said the driver told them that we needed to go back to the hotel to get our passports which was a total lie - if that was the case, why wouldn't he have brought us back to the airport again to make our flight??

Lesson learned: make sure your driver turns off the meter.
