The architecture, specifically the "calçada portuguesa" stone paving and the style of the apartment buildings, strongly suggests Portugal. The vehicles are European models, and the overall climate and bright, clear sky are consistent with a Mediterranean-influenced region. The hilly terrain and dense urban residential layout are typical of many Portuguese cities. I am fairly confident this is in Portugal, likely in the Lisbon or Porto metropolitan areas.

The architecture and the distinctive "calçada portuguesa" stone paving confirm this is definitely Portugal. The residential building style, with its specific pastel-colored facade and shutters, is very characteristic of suburban areas in the Lisbon metropolitan region. The clear blue sky and bare trees suggest a sunny winter day in the Iberian Peninsula. I am quite confident this is a residential neighborhood in the outskirts of Lisbon.
