I will be traveling to Seville, Grenada, Cordoba, Madrid and Barcelona on my own. Other smaller towns with a group, so no need for independent transportation.
The RS guide shared a taxi hailing app, but I would like up to date views from recent travelers.
When not walking, or using Metros, I am satisfied taking cabs rather than uber where it seems more appropriate.
Is there one app for instance that works in all those cities?
