Maria's place is located in an idyllic place. Completely surrounded by mountains but not too far away from a town. Do take into account that you need a car and that the roads have a lot of curves. The little cottage is very well appointed. The bathroom and kitchen are very new. I particularly liked the bathroom very tastefully decorated. For a family of 4 it is ideal. My girls loved to play outside and pet the animals. You are only 15 minutes away from Lekeitio which has restaurants, a beach, supermarkets... For day trip to San Sebastian it is a bit far away. We did it twice but it was a bit too much driving. From Bilbao it is closer. We also went to Laga Beach which we loved.
Maria and her family are lovely and will give you tips on where to go.
