I reserved a transfer from the Barcelona airport 2 weeks in advance of our arrival. Upon arrival I walked to a restaurant in another terminal as instructed. There was no sign of a suntransfer rep. I waited for 20 minutes and called suntransfer. I was told that the driver would arrive in 10 minutes. After 15 minutes I called back. A different rep told me that he was there and left because he didn't see any customers. She asked are you in the right location. I stressed that I was indeed in the right location. Once again, I was told the driver would arrive in 10 minutes. After another 15 minutes, I called customer service again. I was assured that the driver would be there in 10 minutes. At the ten minute mark, I began to gather my things to get a taxi, at which point a driver showed up. In the end I waited for over an hour. Note that this was a private driver that suntransfer must have hired because there he had no suntransfer identification. I will never use them again. Take the airport bus. It runs frequently and is only 4 euro.
