Hi MickG,
You could ask the owners of your accom' to book a taxi for you.
Or, you could phone the local taxi office direct yourself to pre-book.
The very reliable lads are Stamatis, Dimitris and Spiros, they all speak good English.
Contact them on.... 00306972 767803
It should cost between 45-50 euros...cheaper than if you hail a taxi at the airport.
Happy holidays!
Eileen.
