Rebecca - Phill
Eat a lot and swim as much as you can. The prices are a bargain here compared to other Ionian islands, like Corfu or Zante. Four people we never paid more than 50-60 euros for a meal. Argostoli, the capital, was nice for an evening walk but too busy.
Skala was too turisty, Lixouri was fairly nice, but the best village for more was Fiskardo. It was certainly the most busy village in Kefalonia and very expensive but so nice with all these colours, the narrow paths and the port with the yacths.
Ohhh, I miss Kefalonia so much!! Certainly will go back in September this summer.
