If you are visiting Dublin but also hiring a car I would strongly recommend looking to stay a little bit further out. This cottage in Ballymore Eustace is an easy 30 minute drive to the nearby park and ride for Dublin and then another 20 mins by tram.
The benefits are that the cottage is beautifully situated, the village of Ballymore Eustace is only a few hundred metres away with pubs and local shops and the cottage has excellent facilities and is quiet and cosy. I would very much recommend.
