Wintering in Spain

Do you love the Spanish way of life? Me too, and I would like to spend the winter months in good company in Southern Spain, looking for a flatmate for a temporary shared flat (1-3 months) in a holiday apartment/house of our mutual choice. We can decide on the destination together. My idea of a normal daily life 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 romantic relationship this way. The incurred costs should be shared. Arrival by plane from various departure airports or by car would be possible. No pets, please! I would be happy if we used the time to get to know each other better in person beforehand.
