Although Cillian wasn't there to greet me personally, he left detailed instructions and kept in touch over email reliably. His roommates were also very friendly and helpful in making sure I understood and had everything I needed. His house is located super close to the airport and very conveniently to the major busline that gets to Dublin Center. The room itself was spacious and uncluttered. Bed was comfortable enough. If you are looking for an inexpensive place, close to transport and the airport, a little distance out of the center, then I can recommend Cillian's room.
