Wintering in Spain

Do you love the Spanish way of life? Me too! I would like to spend the winter months in pleasant company in Southern Spain and am looking for a flatmate for a temporary shared flat (1-3 months) in a holiday apartment/house of our mutual choosing. We can decide on the destination together. My idea of a normal daily routine includes shopping, cooking, excursions, and cultural activities. I am 65+, female, physically fit, have diverse interests, and appreciate a relaxed coexistence. I am not looking for a relationship through this. The costs incurred should be shared. Travel by plane from various departure airports or by car would be conceivable. No pets, please! I would be happy if we could use the time to get to know each other better in person beforehand.
