Well, we tried Plakias last year because we read some good things about it (mostly from this website).
We had previously been to Kefalonia, Corfu and Ithaka, which we loved, for several years and were looking for somewhere else that seemed a bit similar - laid back atmosphere, good food in friendly restaurants, warm seas etc...
Unfortunately, for us, Plakias did not live up to our expectations. True, the rooms were adequate and the whole village was pleasant to look at, but we found the sea was often too rough, the wind often too strong and the food often poorly cooked and badly presented. We did spend some time driving around to look at other parts of the island but were not very impressed with any of it.
I should say that we have also tried Rhodes (hated it) and Lesbos (quite nice) but so far we have to say the Ionian Islands seem to have got it just right for us.
I am sorry if this upsets some of you but I am sure you have your own reasons for loving Plakias.
