Best sandy beach especially when u are travveling for the beach...not rocks at all...
Agia Marina offers all the facilities you might need being a tourist.
It has what people want on holiday, blue sky, hot sunshine, guaranteed. You have the long street parallel with the beach, with all the shops, tavernas and entertainment. The sea is like bathwater, (warm). The Greeks are nice people, wanting to please, (not every Greek) but hey. It is very cheap in my opinion. 3 course meal 9 euro! Cheap local buses.
