I recommend this accomodation without hesitations.
The house is perfectly clean and lovely, you have your own bathroom. The breakfast is generous and high quality and whatever you're european or not you'll find what you like. It can be served at all time which is enjoyable.
The family is friendly and quiet (so you can sleep late without problems) but really helpfull, they explained me everything I needed (and it was much) about the city and the bus (because the running of the network is quite difficult to understand). But if you have any problems or queries, I'm sure they'll do their best.
Just, dont be allergic to dogs, there is one but don't be scared, she is quiet and nice, just like a lovely plush.
The location is not bad, but you have to take the bus to go to city center, it's around 10/15 minutes by the bus. The location instead is good if you come from the airport, it's around 15 minutes by bus or 12e by cab.
At last, the price is cheap for Dublin.
