the villa had everything we needed and sophia (katerina's sister) was so very helpful and welcoming.
if you want to escape from it all - then the villa arethusa is the perfect place. we loved it and will definitely go back one day.
we would recommend a hire car though unless you are particularly fit and fond of walking as vathi is quite a trek away. we popped into the town every day to get provisions - fresh fish off the fish man and meat from the butchers. then back to the villa to BBQ and enjoy the peace and quiet.
