Although we are not there all year long, we just love the location.
All the basics - bars, banks, pharmacy, supermarket & other shops etc in the local villages - La Alfoquia and Zurgena.
Just buy very carefully with a good solicitor.
Winter lasts about 10-12 weeks when you DO need heating at least early morning & at night - although seasonal weather doesn't seem very predictable anywhere these days! Some folks put rugs down for the winter.
Spend some time in the local bars and have a chat with the locals to build up your own knowledge of they area - rent a place for a few weeks if practical.
Wishing you well
