I had an amazing time at A Fabrica. It's in a beautiful area of Galicia, and is well worth the visit. Sara, Oscar, and their staff are great people and the hours were very fair - I had heaps of time to myself and lots of opportunities to visit the surrounding villages, as well as multiple day trips to Ourense. The work was mainly outside doing general gardening duties such as weeding, trimming hedges, sweeping and other odd jobs, as well as in the hostel doing beds, washing and cleaning. The work was easy and varied.
I'll definitely be back to visit!
