The architecture, with its dense, multi-story buildings and small balconies, strongly suggests an Italian city. The blue street sign is consistent with Italian road signage. The vehicles, including a Fiat and a Lancia, are very common in Italy. The narrow, paved street and the style of the building facades point toward a historic urban center, likely in the southern part of the country. I suspect this is Naples.

I am fairly sure this is Italy.

The blue one-way street sign confirms Italy. The architecture, with its dense, weathered facades and narrow streets, is quintessential Naples. The cobblestone road surface is very common in historic Italian city centers. The density of parked cars and the style of the buildings feel exactly like the Quartieri Spagnoli or a similar district in Naples. I am very confident this is in Naples, Italy.
