This was a shared room in a suburban house in Harmonstown, less than 10min train ride from Dublin's Connolly station. Train fare is 2,60 euro adult one way, or same day return 4,80 euros (as of 2019). Considering how expensive it is in City Center (hotel or Airbnb), this is a great value and convenient. Communication with host was very good. Check-in smooth. Lodging has all the necessities. Recommend.
