My wife and I stayed here on holiday from the United States. Sure, it is a little walk (maybe 10min) from the center of town. The bus stops outside the door, so if you don't mind a bus ride you should be fine.
What makes this place great is the owners. It was sort of like staying with friends. The owner was always available with directions, recommendations. The owner also recommended the Hertz shop down the road (5 minute walk down circular) which was awesome way for us to leave and return to Dublin. When we returned "sure you can use my garage." Which was nice, the 16A bus might come to his doorstep, but it is a LONG bus ride (1hr30min) from the Airport.
Breakfast was good. Our room had a bathroom (en suite as they say). Price was $40 Euro a person. The room was quiet, we were never disturbed! Overall a great experience and I would highly recommend it. As rick steve's might say 1/2 the price for 2x the cultural immersion. Too bad I didn't know yelp was in Dublin before I went (I would of found restaurants!) read more
