ok I have just spent 4 days at this finca! The place is run by a Finnish and an Indian woman, they come recommended by another village that unfortunately had to close down.
Kurkum farm is actually in Aragon (not Catalunya). Kurkum is very much a family affair with added volunteers who stay a few months at a time. They are not currently looking for people to move in permanently. It is a great place with a spiritual vibe and a bursting permaculture-garden.
