I've been to Athens only once. But I remember it as alive and cherful time. Relaxing in the old center, relaxing at the sea. The only one disadvantage was the noise. It was so moisy there. Also people were very loud.

I looked at the antennas next to the sea, on the roofs of small houses. They were fixed just next to the wires with hanging clothes :-) You could look at the water through the antennas :-)
Usually, Greece roofs makes useful part of the house, therefore they are being equipped with balustrades that makes in turn a base for antennas mounting.

They have a problem with antennas. Mountainous centre and close to 2000 islands, it is not small problem in the case of telecommunication signals distribution.
