What is the setting of "Araby"?

The setting of "Araby" is Dublin, capital city of Ireland and hometown of James Joyce. The unnamed narrator lives in a place called North Richmond Street, which is described as "blind." We get a sense of Joyce is referring to as blindness in his description of this respectable but bland part of town. The street is closed off from the wider world, both geographically and culturally. This is a place where nothing much ever happens except for when school is out for the day.
Though outwardly respectable, the boy's family could be described as shabby genteel, that is to say they have come down in the world. One suspects that their relative poverty has forced them to lead an itinerant lifestyle, constantly moving from one rented place to another. It's small wonder, then, that the boy should feel the need to escape from such a chronically unstable existence, that he craves the kind of excitement that only the Araby bazaar promises to give. The boy, like the pupils of the Christian Brothers' school on the street where he lives, wants to be set free, if only for a short time. He wants to leave behind him the stifling, constricting world in which he's forced to live out his formative years.

When the story opens, the narrator describes the street where he lives, namely, North Richmond Street, which is a now well-known road in Dublin, Ireland.  The narrator also references the Christian Brothers' School, which opened in 1829 on North Richmond Street.  This detail helps to confirm that we are in Dublin, Ireland's capital city.  The story appears in James Joyce's collection called The Dubliners, which was published in 1914. However, the story itself was written around 1905 (and this is when it seems to take place).  
The story is written in a first person objective point of view, meaning that the narrator is a participant in the story's events and is narrating them after the events of the story have taken place.  He uses past tense verbs to tell this story of his childhood love and disappointment and to describe how he came to a more accurate understanding of his place in the world.
