We were a large group, a family of 5 (children 14 - 9) and my parents. We spent a lovely relaxing 10 days at villa Katrina. Facilities were excellent, especially the swimming pool, BBQ and fabulous view from the roof terrace. Cannot fault the property and service at all, it had everything we needed.
You will need a car to get around, but there is lots to do. It's an easy drive to Argostoli town to see amazing turtles (and late night shopping) in the other direction, Lourdes is only 20 mins away. Also really enjoyed local beach bar 5 mins down the hill.
Would love to return.
