The old Stone House is well renovated and accommodates easily up to 11 persons (13 is possible but 2 would have to sleep in the kitchen/living). We were with 8, so very spacious. The bedrooms are very nice, clean and all comfort is there. The 3 bathrooms also help a lot (we were with 5 teenagers:)). The yard is a bit fenced off, we initiall parked the cars there but when eating and sitting outside, we had the feeling to sit at the parking yard, so we parked the cars nearby the cute tiny church parking, which gave us a bit more space in the yard.
The location of the house in a tiny village (4 houses and a church) is about 25 minutes from Vitoria and an hour from Bilbao. For any supermarket or other shop Vitoria is nearest so you really need a car.
Great that the house has a large fridge, to avoid having to go to often to the supermarket.
