What is downtown like in in Dublin, Leinster?

Dublin is the beautiful capital city of Ireland, where one can find beautiful Georgian buildings, neoclassical palaces, and modern architecture. It is important to know that, while the city centre of Dublin is relatively small compared to more populous European capitals, the urban sprawl is extreme. Thus, one should consider how close their place of residence actually is to their workplace, since an apartment ostensibly within ‘Dublin’ could quite easily be in a dormitory town 20 kilometres as the crow flies from the outskirts of the city. However, that is not to say that public transport won’t be sufficient to make such a journey efficiently if that is one’s only option.
