What is the difference between getting a transfer or using a street taxi from the airport or the port?

Transfers: This is when you hire a taxi or driver to meet you at the airport(or to the airport, ferry, cruise ship etc). He is there even if your plane is delayed, knows where you are going and takes you there for a previously agreed upon price. Transfers from the Airport to the center of Athens costs around 55 euro and from your hotel to the port around 35 euro. I always use transfers because arriving in a foreign city is disorienting enough, it's nice to know you can get to your hotel without a hassle. It's like having a friend meet you at the airport. The other option is getting a street taxi from outside the terminal for about 25-30 euro. The problem with these guys is that you may get one who is great.  more
