Sackville Place still exists, running east off O'Connell Street.
And from Wikipedia:
O'Connell Street (Irish: Sráid Uí Chonaill) is Dublin's main thoroughfare. It measures 49 m (160 ft) in width at its southern end, 46 m (150 ft) at the north, and is 500 m (1650 ft) in length. Known as 'Sackville Street' until 1924, it was renamed in honour of Daniel O'Connell, a nationalist leader of the early nineteenth century whose statue stands at the lower end of the street, facing O'Connell Bridge.
