Have used Uber all over Kyiv...as previous poster said, efficient but no English is the norm...actually got a ride in a Tesla heading back from the WW2 museum! Be careful where you try and access...have had cancellations on precoordinated pickups coming out of the InterContinental due to traffic congestion during rush hour.

Uber was fine in Guadalajara as well...my driver had to deviate from the route from the hospital to the airport due to a massive wreck...I started to wonder about the back streets but then, we popped out right at the airport!

Uber is/was supposed to be in Frankfurt, but couldn’t find the authorized pickup point and just went with a taxi.
