Is it easy to catch taxis at Madrid's Airport, the Atocha Station in Madrid and Barcelona-Sants Station in Barcelona?
We are planning on using taxis to get to our hotels from each of those locations. Not sure if I should pre-book taxis or will it be relatively quick to grab one outside of the airport or station? I have traveled to some places where there are large lines to grab a taxi, so it is well-worth the prebook.
Thank you!
