We are a family of 2 adults and 3 children. We stayed at this villa for 3 weeks in June-July 2018. The house has everything you need, maybe except iron, big towels and wifi. But The owners told us this before the arrival, so no cheating;)
The owners were very friendly and kind, they are always ready to answer 100 questions and more:)
The villa has a big garden, but it is difficult for children to walk and play there since the grass is not soft at all.
The place is about 7-10 minutes to the sandy beach by car. The same distance is to supermarkets and the center of Castellamare.
