There are different definitions of a neighbourhood. The one I like best is the one that defines a neighbourhood as the community of inhabitants of a part of the city. Urban planner Kevin Lynch, in his book The image of the citydefines them as those sectors that form the city with an identifiable image. And I think he is absolutely right. I look around me and in this street Vallirana, one of the quietest in Sarrià-Sant Gervasi, I see familiar faces, children playing in the square, the usual shops, worn-out urban material and in the background, there is that peace of those who feel at home, in their comfort zone. In his neighbourhood. His own oasis in the city.
