Julian’s place was my favorite AirBNB stay thus far. He runs it it with the cleanliness, hospitality, and efficiency of a German or Swiss Gasthaus. I didn't get the impression that he was doing this solely for the money. I believe that he truly enjoys engaging with his visitors. I would stay again in a heartbeat.
One note: you should be comfortable with a bit of Spanish or French, or be prepared to use Google Translate. Don't worry, he's patient with communication.
