Months 0–3: Visit, properly
Multiple visits, ideally in different seasons. A summer trip and a winter trip will tell you very different things about whether you’d cope. Stay for at least a week each time. Walk the village in the morning, evening, weekday, weekend. Talk to people. Eat the food. Test the heat (or the cold).
Cost: usual travel costs. Budget €1,800–3,500 per visit including flights and accommodation, depending on origin.
