We stayed at Magdalena's and Bruno's place the night before we had to fly back home early in the morning and that was the best decision! The airport was very close by car and Magdalena and Bruno helped us a lot with information about where and how to fill up and return our car. The room we stayed in wasn't big but very cozy and clean and that was exactly what we needed for such a short night. We shared the bathroom only with another Airbnb room which worked very well. The only additional advice I would like to give you is don't try to wash your hair there if it is long and you are used to a decent amount of water pressure (which is quite a general problem if you aren't from Ireland or the UK but here it felt especially low but this could also be caused by the late time). So in general I would totally really recommend staying at Magdalena's and Bruno's home if you are looking for a calm place a little outside of Dublin and especially if you are looking for a place close to the airport. They are the most welcoming and nicest hosts you could imagine!
