Hey pip100,
Can,t say I am well up on
Itrabo. I guess you have checked out the info on this site? I am sure as with us you have researched the area well. The only advice I can give is visit, visit and visit again, maybe rent a place on a long term let for a while before commiting fully. Make sure you visit at different times of the year so you can be aware of all weather conditions as they can vary more inland than on the coast. The Alpujarra region generally is such an awe inspiring place, climate, people, habitat and scenery are all wonderful. I wish you well in your search and would be most interested to hear how you get on.
Much love
