Our stay there was very enjoyable. The house is 5min walk away from very relaxed beach. 10 min walk to restaurants in the village. The location is within the sand dunes, surrounded by old trees. Road nearby is not busy at all. You have a lot of privacy and a lot of space, enough even for 6 people!
Almost everything is self-built and self-made. There is big TV with netflix, decent audio appliances, massage chair (!), two bathrooms and fully equipped kitchen. All rooms have working air conditioning. Outside you will even find a shower for cleaning the beach sand as well as a hammock where I spent quite a few relaxed hours.
Nearby village offers places to eat and drink for good money, there is windsurfing school around as well as good sunbeds for not more than 3€. The drive from Airport takes around 20min and you can use bus if required.
The owners gave us a very warm greeting, explained everything necessary and helped out whenever it was needed. They both speak excellent english so there was no communication problems at all.
There is always some room for improvement: some items outside could be tidied up, few doors did not close anymore (or did not open :) ), I personally found the bed pillows uncomfortable. You also need to understand that an airport nearby means also air traffic, which did not disturb us so much. But all in all it was a marvelous stay and we recommend it wholeheartedly to anybody considering having few days off grid in Kos.
The owners should definitely offer their massage therapy straight away incl. prices - this is kind of missed opportunity for them!
