This is a classic small Italian square. It is full of life and no larger than it needs to be. This is evidently a highly successful social space.
Notice that the surrounding buildings are taller than the square is wide, and they may even be taller than the square is long. (The elevated position of the photographer suggests that the square is no deeper than what we see, as he was probably standing in a window.)
Notice how narrow the street is leading into the square. This is probably one of the densest parts of Genoa, a city that is sandwiched between steep hills and the Ligurian Sea. Space was at a premium in this city, but it doesn't suffer from the necessary economical use of buildable land.
