We stayed in Dublin only a short time, but this apartment is very centrally located and very easily accessible to the airport by bus (40-60 minute trip, depending on time of day). The lodging was a bit cramped, with a small gap next to the right side of the bed, but no way to get out without crawling over the person on the left side. This was not readily apparent from the photos. The shower is also very small, and the bathroom wasn't the cleanest and smelled of mildew.
Dean and Mario were very flexible about our late arrival, and the instructions for finding them very very clear. They also included all of the necessary access codes for the gates and doors on the key ring they provided us, which was very helpful. They also had a cabinet with maps and brochures, a kettle, tea, power converters, and even cold medicine. The bed was decently comfortable and clean, but seemed like a memory foam topper rather than a memory foam mattress.
Would recommend mostly for the location.
