We are living in the countryside by the lake Peurunka. The area is peaceful and sparsely populated but we have nice neighbours close to us.
Our wooden house (200+ sqm) is built in 1980 and extended&renovated 2009. We have 6 bedrooms, a large living room, a spacious kitchen with dining room, 2 bath rooms and a sauna indoors. We have also a big terrace on the lakeside of the house. Just 20 meters from the house we have an own sandy sunny beach (in  the south west direction) perfect for children. The daytime temperature of the water in the lake is 21..23 C in July. By the lake we have a bigger sauna. The house is surrounded by a big garden.
We have a few kayaks,a rowing boat (e.g. for fishing on the lake), table tennis and other outdoor equipment available. One can paddle or fish on our lake or walk in the woods just out of the house. A few kilometers away is a golf range and rapids ideal for fly fishing.
Our  cars are available, the bigger one is Toyota Avensis Verso with seats for 7 persons and the other is Toyota Corolla. Safety seats for children are available too. 
We wish a holiday destination with good possibilities for walking/hiking on the mountains.
