This place is very close to the airport and it costed €17 from airport around 9pm and €14 to the airport around 4.30am. The host helped to book a taxi as it was early in the morning ride to the airport. Besides, the #27 bus (about half an hour intervals) just directly outside the house that takes you to the city in 40 minutes at €2.70 single ride, make sure you have exact change though. As this place has a few rooms are rented, you may also meet people from different side of the world. I met 2 couples from the US and Germany during my 2 night stay over in Dublin. As this place has a poor sound insulation, you may need to have ear pluck if you are a light sleep. Cheers and Dublin is an easy travel city.
