"Sun Villas" in the Svoronata area of Kefalonia are a collection of villas which sleep 6 people in 3 bedrooms. These pretty villas each boast their own private pool, with a terrace and lawned gardens to muck around on in the sun. When you collapse into a sun lounger, you'll get to experience some good views across the Ionian Sea.
Should a day the beach beckon you, there's a choice of two beaches nearby: St Helis and Avithos beaches are both within 3 kilometres of Sun Villas. Argostoli, the capital of Kefalonia, is fairly close to Sun Villas too - and takes around 15 minutes to reach in the car.
