For me it's a friendly community coffee shop, small corner shop in case I need emergency supplies and I can't use my car, and green space nearby (country park/countryside). Those are really my top three I can't compromise on, but what are yours/what am I missing?
I thought about walking proximity to a train station so I can commute to the nearest city, but I'm packing in being close to a city deliberately so maybe this one isn't so crucial!
