We had a wonderful stay at Piero and Marzia's property. The cottage is beautifully and tastefully decorated, with a lovely terrace and sweet little pool which our kids (5 and 3) loved splashing in. The kitchen is small but has everything you need to cook. We were there in late May and the pool was comfortable to swim in. Marzia and Piero live in another wing of the house; they are available but keep a discreet distance except to water the garden, etc. They were very friendly and helpful.
You're only a five minute drive from Fiskardo and a good little supermarket there, as well as all the lovely restaurants, etc. Foki beach, just a short walk from the property (although with two small children, we drove!) is absolutely brilliant, with lovely walks and fantastic snorkelling, as well as plenty of shade in the olive grove next to the beach. There's also a brilliant, traditional family taverna just up from the beach there.
There are loads of things to do nearby, from spending time in Fiskardo to wonderful beaches (we especially liked Jerusalem beach with its fabulous taverna, and Dafnoudi beach). Ionian Discoveries have an unmissable day's boat trip which is a must-do. The taverna in Magganos, just a kilometre or two away, will do any of their food as takeways which was great for a family with small children. A hire car is an essential if you're staying at this property.
The only downsides we found to this property were the lack of air conditioning in the bedrooms, which were rather warm even with shutters kept closed all day, and there is no sea view from the terrace. But we warmly recommend as a wonderful place to stay.
