We spent 3 nights at the end of December in Jorge's chalet mountain house and we loved the remote off-the-grid location. The property and especially the views were spectacular, and inside the house was nice and perfect to relax.
Jorge was a wonderful host and very friendly. He showed us the road to the house, and we followed him with the car, so it was easy to find it. A dirt road leads up this very private property, but it has many potholes and errosion to drive around, so if you are planning on leaving the house everyday, keep in mind the drive to nearest village of Puigpunyent takes about 20 min.
However, the house had a nice pool (we didn't use because of winter) and there are lots of great hike trails right around the house, so plenty to do on-site. We enjoyed cooking in the kitchen and sitting around the fire in the evenings.
It was cold in the house without a fire, so keep in mind this is how you need to heat it. Takes some work but we didn't mind. You will also need to know some tricks about the electricity (mainly solar power, in winter you need to use the gasoline generator), water supply, and should know how to start a good fire. If you love nature, have some DIY skills and don't expect hotel-like comforts, then this is a wonderful place to get away from it all.
