I had a fantastic time at Ciaran's apartment. It was very clean, very roomy, and close to many of Dublin's tourist attractions (such as the Chester Beatty Library, Dublin Castle, and Trinity College). We almost always walked on foot, and never found it a strain. There are also two convenience stores nearby, so that was very handy. Overall, a very nice and safe neighbourhood. I would recommend Ciaran's apartment, especially if you are travelling with 3 people or more (I'd say about 5 people could stay here comfortably).
