I have to get from the airport to the center of Barcelona. Since I am flying alone, I have no one to help me with my suitcase, which is very heavy. The taxi fares are very high, I will go broke on this trip. I searched all over the Internet and finally decided to use GetTransfer https://gettransfer.com/en/directions/spain/barcelona/airports/el-prat. Have you used this service? Which transfer service do you use when you arrive at Barcelona El Prat airport?
