Grainne's place was really spacy and sweet, we really felt like home and there is literally everything you need in her place (tea, honey, hairdryer, EVERYTHING), the place is not that far away from the centre, you can take the bus to get there and it is like 15mn, and 45mn by walk which pretty cool if you wanna eliminate all the beers you drunk during the day ;-)
Our stay was perfect and we will probably get to Grainne's place if we come back to Dublin !
