To be honest, I don't remember how I got to the airport because we came by train from Rome. Then from Venice we flew to Barcelona. Ok I remembered now, I asked the Hotel guy if he can get me a Cab and in the morning, the cabby was there waiting for us. I think it was like 48 Euro for the both of us. That's what we paid in Rome to get to the airport. There Cap fees are regulated and I am not sure if they finally got the UBER.
