Some might call it a luxurious, two-story treehouse. Others would say it's the first geodesic dome in Cantabria. Anna and Juan call this place their little piece of paradise.

The owners wanted to share their love for nature. Indeed, every element here—from the jacuzzi with stunning views to the local products served for breakfast—highlights their passion. The guests' rest is undisturbed by city lights. There are no shops or streets. There are beautiful views of the valley, forests, and mountains. Time to recharge. The trails invite joint adventures—visits to the prehistoric Sopeña cave and walks to the Pozos de Noja lagoon. High in the mountains of the Miera Valley, in northern Spain, Anna and Juan have created an intimate paradise hideaway with couples in mind.
