The architecture, specifically the style of the balconies and the tiled roofs, strongly suggests a Mediterranean European country, likely Portugal. The cobblestone sidewalk (calçada) is a very common feature in Portuguese urban areas. The overcast sky and general urban density point towards a mid-sized city or a suburban area near a major hub like Lisbon or Porto. I am fairly confident this is Portugal.

I suspect this is in Portugal, possibly in the Lisbon metropolitan area. I am 60% sure.

The sign clearly displays "Lusiadas Hospital," which is a prominent private hospital network in Portugal. The architecture and the specific style of the street layout confirm a Portuguese urban environment. Given the branding, this is likely near one of the Lusiadas hospital locations, such as the one in Porto or Lisbon. The residential surroundings suggest a quiet, established neighborhood.

I am in Portugal, likely in Porto near the Lusiadas Hospital. I am 85% sure.
