Very interesting and special stay. We didn't had the chance to meet Maria, but spoke with her on the phone several times, she was lovely and very attentive. We did meet her husband Alex, who run the coffee-restaurant about 50 meters from the house, he was charming, open, great natural host, and helped us in everything we asked or didn't ask.
The internal architecture is beautifully made, really uncommon, and provide a different experience comparing to all places we met before. The place run only on pure green energy, and it is encouraging to see from close that a comfortable house can function in these conditions, it is built from very thick stone walls, thought and built to create natural air flow, but still can get a bit warm inside when there are extremely high temperature outside, because there is no air-condition. Otherwise it is perfect!
