We, a family with 2 children (3yrs and 5 yrs), spent 12 wonderful days at Valentina's and Dimitris' place in May. It was just the perfect place for us - the house was perfectly clean and had everything we needed, the kids loved to play in the garden (very safe, because the pool is shared with a neighbouring place and is opposite of the street - so no risks to fall in for the kids!) while we could relax on the terrace. The place itself is just amazing, decorated with love, and the fridge was filled when we arrived (and there were very yummy avocado-chocolate cookies and muffins, thanks again!). Towels, beach toys, everything you may need you will find there. Valentina and Dimitris came with their kids during the week-end to welcome us which was really nice.
The beach is at a very short walk and Plakias has everything you need (supermarkets, restaurants, shops). We went to various beaches in the area and they all have their own charming character and are well suited for children.
Short: We can fully recommend this place for a family holiday and hope to come back soon!
