I spent only (and "unfortunately"!) 2 nights at the Ecovillage. And It was awesome. Of course you should love nature, rustic environment and life in community. But if you like them, you will be fully satisfied to share a part of this wonderfull Ecovillage life ! The house is kind of "magic", room very confortable, shower and kitchen really beautiful. The meals (breakfast and dinner) are wellness and huge. It's definitively a peaceful place, closed to Sintra historical center. It's better if you have a car. Otherwise, I deeply recommended this place to stay!
