You may call abroad and domestic using special cards. You can buy it in many shops. For about 5 Euro you have about 2 - 3 hours when calling in Europe or US.
What is important:
1. When using street booths (boxes, kiosks) you must remember that they are public. It means that you may talk not more than 40 minutes during one call becasue everyone has a right to talk as it is public phone.
2. There are usually long queues, especially in the evening, so you need to patient.:)
Ammoudi - A small port at the bottom of the cliff
After viewing the sunset we were supposed to meet our VT friends for dinner at the Sunset Restaurant in Ammoudi. Ammoudi is the small port for Oia at the bottom of the cliff. As I mentioned before we decided to take a bus and not hike to Oia. However it was obvious as we looked over the cliff to Ammoudi that we still had to do quite a hike to get there. As a matter of fact there were 300 steps down the cliff to Ammoudi.
Oia is a magical little spot on the right side (as you look out from Santorini) of the caldera. The big draw here for a lot of people to walk out and catch the sunset on the steep cliff and the ruined castle. You'll be joined by thousands of other fellow sun worhshippers who grow quietly awed by this beautiful spectacle. Crowded? Touristy? Yes! But still very nice to see.
