There is a street, near where we live now, that I have always thought is the nicest street in Milan (apart from the obvious Via della Spiga, etc.).
The street is fairly quiet, not a main thoroughfare; it has some beautiful apartment buildings; it’s close to all the things I like (Sento – the Japanese restaurant; the Imperiale – the Chinese restaurant; K2 – the Tuscan restaurant – oh, they all seem to be restaurants!); it’s very walkable from the city centre; it’s close to the dog walks and the park.
